**Welcome to the Mathematics Department!**

Our research specialties are in algebra, analysis, geometry, probability and topology.

There are about thirty-five research faculty members and almost seventy graduate students in the department.

The American Mathematical Society has ranked us in the top group of U.S. research departments in Mathematics.

Six members of the department were named Fellows of the American Mathematical Society in 2013. Three members of the department spoke in the Lie Theory Section of the 2014 International Congress of Mathematics.

We also take great pride in the quality of our outstanding undergraduate teaching as well as our thriving graduate program.

The EUGENE MATH CIRCLE is continuing in the department. It is aimed at elementary, middle and high school students who enjoy math and want to be stretched by challenging problems.

## Mike Price wins Tykeson Teaching Award

Congratulations to Mike Price for winning the College of Arts & Sciences Tykeson Teaching Award.

## Leahy Endowment Fund

A new fund, the Leahy Endowment Fund, has been created in honor of the long term department member, John Leahy, who passed away on January 29, 2015. The fund is “for the broad purpose of supporting mathematics graduate students” and it will remain open for contributions for about one year. Contributions should go to the UO Foundation “in memory of John Leahy.”

## AWM Distinguished Speaker

Lan-Hsuan Huang from the University of Connecticut will be on campus May 7 – 8th. She will give an undergraduate and a research talk as part of the AWM Distinguished Speaker series.

Undergraduate talk – Thursday, May 7, 3 PM, Deady 102

Title: Why are soap bubbles round?

Abstract: You would be surprised if you saw a soap bubble shaped like a duck, wouldn’t you? But why are all soap bubbles spherical? We will explain the mathematical model of soap bubbles, which are called “constant mean curvature surfaces”. We will discuss the classical Alexandrov theorem, which says that a smooth surface with constant mean curvature that encloses a finite region of space and doesn’t intersect itself has to be a sphere.

Research talk – Friday, May 8, 4 PM, Deady 208

Title: A tour to the Positive Mass Theorem and beyond

Abstract: The Positive Mass Theorem has been a cornerstone of mathematical general relativity since the resolution of the three dimensional case in the 80’s. In this talk, we begin with a calculus proof of a special graphical setting of the theorem. After providing the necessary background in differential geometry, we then discuss both the classical results and recent progress toward the more general case, as well as the stability statement of the theorem.

## Ph.D. Candidate Receives NSF Post-Doc

The Department congratulates graduating Ph.D. candidate Nathan Permutter on receiving a postdoctoral fellowship from the National Science Foundation. Nathan is working in Algebraic Topology with Professor Boris Botvinnik. After graduating this spring, Nathan will pursue his research at Stanford University.

## Pacific Coast Gravity Meeting

The Institute for Theoretical Sciences, the Mathematics Department and the Physics Department at the University of Oregon are hosting the 31st Pacific Coast Gravity Meeting on March 13-14, 2015. For information, visit PCGM.
