The Department of Mathematical Sciences enjoys an active Colloquium series. There are also departmental research seminars in Analysis and Discrete Mathematics. All our events are open to students and the public, and are free to attend unless otherwise indicated.

## Fall 2019

**Colloquium**

- Steve Bell, Purdue West Lafayette,
*The Theorem that is Too Good To Be True and How it Made Me Very Happy*,**Friday, Oct. 4**, 4:00-5:00 in Kettler 146.- This colloquium talk is the opening event in the 2019 Midwestern Workshop in Asymptotic Analysis, Oct. 4-6.

- Xin Dong, University of California, Irvine,
*Bergman Metric and Cauchy-Riemann Equations*,**Monday, Sept. 16**, 11:00-noon in KT 218.

## Spring 2019

**Colloquium**

- Eric Baer, Carnegie Mellon University,
*The Isoperimetric Inequality and Some Results on Symmetry in Geometric Problems from the Calculus of Variations*. April 3.- Many mathematical models in the physical sciences involve understanding how nature balances the cost of enclosing a volume of material with the amount of material to be enclosed. One fundamental tool used to understand this balance is the isoperimetric inequality, a classical result showing that for sets of fixed volume, perimeter (or surface area) is minimized when the set is a ball. We will see how the tools of mathematical analysis (calculus) and the calculus of variations interact to establish inequalities of this type, and what they tell can tell us about models of real-world phenomena.

- Alyssa Genschaw, University of Missouri - Columbia,
*An Introduction to Caloric Measure*. April 2.- We first give an introduction to harmonic measure. Harmonic measure can be described from two different points of view: a probabilistic interpretation or a solution to a boundary value problem. We then define caloric measure and discuss some similarities and differences to harmonic measure.

- Alan Legg, Purdue University Fort Wayne,
*Some Useful Ideas from Complex Analysis*. April 1.- The field of complex analysis finds wide application both within mathematics and in science generally. I'll give an overview of some ways in which ideas from complex analysis can help simplify and resolve questions. A special emphasis will be given to the idea of conformal mapping, where complicated shapes in a problem can be replaced by nicer ones while preserving the integrity of the problem.

- Peter Dragnev,
*The Mastodon Theorem - 20 Years in the Making*, Feb. 6.

### Analysis Seminar

- Adam Coffman,
*Isolated CR singularities of n-manifolds in*, March 20.**C**^{n} - Yifei Pan,
*A Unique continuation result on total differential of high order and Hardy type inequality*, Feb. 18. - Martino Fassina, University of Illinois Urbana-Champaign,
*Non-solvability of differential operators in the flat category*. Jan. 28.
