### MATH 475: History of Mathematics

Jenia Tevelev TuTh 2:30-3:45

Prerequisites:

Math 233 and Math 300 or CS 250.

Text:

"A History of Mathematics" by V. Katz

Note:

This course satisfies the General Education IE requirement for Mathematics and Statistics.

Description:

This is an introduction to the history of mathematics from ancient civilizations to present day. Students will study major mathematical discoveries in their cultural, historical, and scientific contexts. This course explores how the study of mathematics evolved through time, and the ways of thinking of mathematicians of different eras - their breakthroughs and failures. Students will have an opportunity to integrate their knowledge of mathematical theories with material covered in General Education courses. Forms of evaluation will include a group presentation, class discussions, and a final paper.
The math major is made up of technical courses on the theory of mathematics from Calculus to more complex concepts. This course is unique in providing a humanities-based approach to understanding math. For example, students are required to use primary sources on a weekly basis. Students study examples of how mathematical advances were made in response to or alongside developments in other branches of science - such as Ptolemy’s work in trigonometry being motivated by applications in astronomy, and Newton as the father of both calculus and modern physics. Students also learn to understand mathematicians as people of their times - for example, how Babylonian mathematicians were motivated by the needs of the empire, or how Evariste Galois was both a brilliant mathematician and a passionate French revolutionary. Additionally, many math majors go on to teach mathematics after graduation, and in this course the history of math is is studied in the context of the history of education.
The homework assignments contain a component where students are required to write short compositions. Many of these assignments will ask students to engage in self-reflection on how their study of the history of mathematics in the current course is influenced by the General Education courses they took. This is not limited to courses carrying the Historical Studies designation, but Economics, Sociology, Science and other modes of human thought all present lenses through which one can study the mathematics and mathematicians that are the focus of the course; the homework assignments will invite students to apply all of those lenses to the topics at hand. Students will also be required to write an interdisciplinary 20-page final essay. Essay topics are developed by the student with assistance from the professor. Students draw not only on their mathematics coursework, but also on the knowledge they have accrued from other GenEd curriculum courses they have experienced in their first two years of college. After seeing how mathematical tools have developed in conversation with history, culture, and science, students can better appreciate the uses and possibilities of advanced mathematics.
A substantial fraction of the course grade is based on a class presentation; this is a major change from standard upper division math/stat requirements. Each group, which typically consists of three students, collaboratively researches and presents an interdisciplinary mathematical topic, chosen by the group from the instructor’s list of suggested topics. This is highly unusual for mathematics classes, where problems are typically presented abstracted from their scientific and cultural roots. These presentations are spaced out throughout the semester, and the students’ work is referenced and discussed in a class discussion later in class.
Additionally, highly unusually for a mathematics course, a large part of the course grade is based on participation in class discussions. Each week, the students are assigned readings. A large amount of weekly class time is devoted to a roundtable discussion of the reading - its implications for modern mathematics, how it was understood at the time, mathematical concepts in the reading, and the close-reading of assigned passages.

"Essentials of Stochastic Processes" by R. Durrett

Description:

This course is an introduction to stochastic processes and Monte-Carlo methods. And we will use from time to time some more advanced concepts from analysis and linear algebra. One of the main goal in the class is to develop a "probabilist intuition and way of thinking". We will present some proofs and we will skip some others in order to provide a reasonably broad range of topics, concepts and techniques. We emphasize examples both in discrete and continuous time from a wide range of disciplines, for example branching processes, queueing systems, population models, chemical reaction networks and so on. We will also discuss the numerical implementation of Markov chains and discuss the basics of Monte-Carlo algorithms. Among the topics treated in the class are

Simulation of random variables. A first look at Monte-Carlo algorithms.

Markov chains on discrete state spaces (both finite and countable). Definition and basic properties, classification of states (positive recurrence, recurrence and transience), stationary distribution and limit theorems, analysis of transient behavior, applications and examples.

Description:

The aim of this course will be to give an overview of the mathematical background, physical applications and numerical computations associated with a number of prototypical wave systems both at the continuum and at the lattice level. We will start from finite dimensional Hamiltonian systems, discuss their symmetries and Lagrangian/Hamiltonian structure, and then extend considerations to infinite dimensional systems of partial differential and differential-difference equations. Prototypical case examples will be the continuum and the discrete nonlinear Schrodinger equation, the Korteweg-de Vries equation, the sine-Gordon equation, and the Fermi-Pasta-Ulam lattice, among others. We will examine the symmetries, conservation laws, solitary wave solutions, linearization spectral properties and dynamics of such equations and attempt to connect them with physical applications from nonlinear optics, fluid mechanics, materials science and atomic physics, as well as develop computational tools (such as bifurcation analysis and time-stepping algorithms) about how to address them. Time permitting, we will also make short excursions to systems of multiple components, higher dimensions or of dissipative character (e.g. reaction-diffusion type) to discuss some similarities and differences with these.

geometry. The basic techniques of Kahler geometry, Hodge theory, line and
vector bundles, needed for the study of the geometry and topology of complex projective
algebraic varieties, will be introduced and illustrated in basic examples such as Riemann surfaces, algebraic surfaces, abelian
varieties, and Grassmannians.

### MATH 797DC: ST-Derived Categories

Jenia Tevelev TuTh 10:00-11:15

Prerequisites:

Math 612 and any introductory course in Algebraic Geometry

Recommended Text:

Huybrechts, Fourier-Mukai Transforms in Algebraic Geometry

Description:

The course will consist of two parts of roughly the same length. The first part will cover basics of Abelian, triangulated and derived categories using examples from algebra. The only prerequisites for this part are Math 611-612. The second part will be more technical as we will focus on computations and applications of derived categories of coherent sheaves in algebraic geometry. The prerequisite for this part is a standard course in algebraic geometry, either using the language of schemes (Chapter II of Hartschorne will suffice) or complex algebraic geometry (e.g. the first volume of Voisin’s "Hodge theory and complex algebraic geometry”). The course will end with students’ group presentations prepared with the help of the instructor.

The course grade will be based on the homework and the project. There will be 5 biweekly homework sets. Problems will be worth certain number of points depending on their difficulty with a total of 30 points for each homework. To get an A you have to accumulate 100 points by the end of the semester. Homework problems can be either presented during office hours
or written down and submitted.

### STAT 608: Mathematical Statistics II

Daeyoung Kim TuTh 1:00-2:15

Prerequisites:

STAT 607 or permission of the instructor.

Text:

Statistical Inference (second edition), by George Casella and Roger L. Berger

Description:

This is the second part of a two semester sequence on probability and mathematical statistics. Stat 607 covered probability, discrete/continuous distributions, basic convergence theory and basic statistical modelling. In Stat 608 we cover an introduction to the basic methods of statistical inference, pick up some additional probability topics as needed and examine further issues in methods of inference including more on likelihood based methods, optimal methods of inference, more large sample methods, Bayesian inference and Resampling methods. The theory is utilized in addressing problems in parametric/nonparametric methods, two and multi-sample problems, and regression. As with Stat 607, this is primarily a theory course emphasizing fundamental concepts and techniques.

### STAT 691P: Project Seminar

John Staudenmayer MWF 9:05-9:55

Prerequisites:

Permission of instructor.

Text:

None.

Description:

This course is designed for students to complete the master's project requirement in statistics, with guidance from faculty. The course will begin with determining student topics and groups. Each student will complete a group project. Each group will work together for one semester and be responsible for its own schedule, work plan, and final report. Regular class meetings will involve student presentations on progress of projects, with input from the instructor. Students will learn about the statistical methods employed by each group. Students in the course will learn new statistical methods, how to work collaboratively, how to use R and other software packages, and how to present oral and written reports.

### STAT 797L: ST-Mixture Models

Daeyoung Kim TuTh 2:30-3:45

Prerequisites:

Calculus based Probablity and Mathematical Statistics (preferably Stat 607-608 or rough equivalent), and Regression Modeling (preferably Stat 625 (previously Stat 697R) or rough equivalent).
Stat 608 is a co-requisite for this course.

Description:

A challenging task of statistical analysis is to handle complex data structures including heterogenous data, correlated data, overdispersed data and hierarchically structured data.
Mixture/Latent variable models provide a natural framework to analyze such complex data sets and identify hidden patterns in the data.
This course will focus on introducing the ideas and theories of mixture/latent variable models and their applications in various areas such as biology, medicine, genomics, epidemiology, social and psychological sciences, marketing, economics and finance.
Topics will include the (parametric/finite/nonparametric) mixture/latent variable model specification, identifiability, estimation methods, large sample properties, finite sample properties, computational algorithms, data analysis, and interpretation.
This course will be accessible to students with knowledge of statistics at an intermediate level (i.e., probability, basis for the statistical inference and regression analysis).
