The Department of Mathematics and Statistics is a community of scholars committed to excellence in research and instruction. We offer a comprehensive set of curricula in our disciplines, from introductory-level general education courses to doctoral dissertation direction and postdoctoral mentoring. Undergraduate majors enjoy a broad array of options through which they can earn the bachelor's degree, and can also apply to participate in summer research activities. The Department's Ph.D. program appears among the top public graduate programs in the recent National Research Council rankings. The M.S. programs in both Applied Mathematics and Statistics contribute to an important pipeline of professionally trained students who enter the high-technology industrial sector.

### February 2017

Professors Tom Braden and Eric Sommers, as well as Visiting Assistant Professor Jacob Matherne, attended the 2017 Joint Math Meetings which took place 5-8 January in Atlanta, Georgia. Each spoke in the special session on *Representations and Related Geometry in Lie Theory*. Tom's talk was titled "A sufficient condition for a category of perverse sheaves to be highest weight," while Eric's was "Functions on nilpotent orbit covers," and Jacob's was "A combinatorial Fourier transform for quiver representation varieties in type A." Matherne spoke on this topic earlier in a 2 January research seminar at the Indian Institute of Science Education and Research (IISER) in Pune, India, and later at the Erwin Schrodinger Institute in Vienna, Austria, where he attended the * Geometry and Representation Theory * workshop 16-27 January. While in Pune, Jacob also talked about countability and uncountability with 8th, 9th, and 10th graders at the New English School, and he discussed careers in mathematics with beginning undergraduates at Modern College.

Professor Franz Pedit gave an inaugural address at the vernissage for the University of Tuebingen's perpetual exhibition *Mind and Shape* on 19 January 2017. A trio of computer graphic images - "Dini Surface, Tetranoid, and Twizzled Torus" - produced by Dr. Nicholas Schmitt (who was Prof. Rob Kusner's first Ph.D. student at UMass) were permanently loaned to the exhibition. Franz also received funding (with Michael Wolf from Rice University) to co-organize a 5-day workshop for 42 prticipants on *Higgs Bundles and Harmonic Maps of Riemann Surfaces* at Casa Matematica Oaxaca, Mexico, scheduled for 1-6 July 2018.

On 2 December 2016, Professor HongKun Zhang delivered an invited *Fields Dynamics Day* talk on "Optimal bounds on correlation decay rates for nonuniformly hyperbolic systems" at the Fields Institute in Toronto, Canada. This event brings together experts in the field of dynamical systems to report on the their latest advances. The speakers reflect the broad influence of dynamical systems in all fields of mathematics, with a common theme being the relation between dynamical systems and probability theory. She also co-organized a Special Section on *Stochastic Properties of Dynamical Systems* with Jacopo De Simoi and Ke Zhang (both from U. Toronto) at the 2-4 December 2016 Canadian Mathematical Society winter meeting in Niagara Falls. Dmitry Dolgopyat, a leading expert in dynamical systems from U. Maryland, was among the 13 mathematicians who gave talks in this special section. Dmitry and HongKun (together with Mark Demers and Konstantin Khanin) received funding to hold a workshop on *New Developments in Open Dynamical Systems and Their Applications* at the Banff International Research Station, scheduled for 18-23 March 2018.

A group of faculty, staff, and students in the department has formed a Diversity Committee to celebrate our diverse population. For more information - or to join the group - please contact Professor Krista J Gile.
