INTRINSIC PROPERTIES OF GRAPHS EMBEDDED IN 3 ERICA FLAPAN, Editor in Chief of the Notices of the American Mathematical Society Knot theory is the study of embeddings of simple closed curves in 3 . A natural extension of knot theory is the study of embeddings of graphs in 3 . However, in contrast with knots, the structure of a graph can be complex, and this can affect all of its embeddings. If every embedding of a graph has a particular property, then we say that property is intrinsic to the graph. For example, a graph is said to be intrinsically knotted if every embedding of the graph in 3 contains a knot. In this talk I will introduce intrinsic knotting and other intrinsic properties of graphs, and present some open problems in the area.

Aaron Brown, University of Chicago Recent progress in the Zimmer program Abstract: The Zimmer program refers to a number of questions and conjectures about actions of certain discrete groups, namely, lattices in higher-rank simple Lie groups. The primary example example of a such a group is SL(n,R). In the past few years, there has been significant progress in the Zimmer program. In my talk, I will discuss a recent proof of Zimmer's conjecture which shows that (cocompact and certain non-uniform) higher-rank lattices do not act on manifolds with low dimension. I will also discuss recent results and work in progress that classify all possible non-trivial actions under certain dynamical or dimension assumptions.

Wesleyan's Undergrad Math Club Presents: The Math of Gerrymandering Abstract:In Gill v. Whitford , a Wisconsin court struck down the state assembly map as unconstitutional gerrymandering. Will the US Supreme court uphold this landmark ruling? The plaintiffs case hinges on elementary mathematics, including a simple new efficiency gap formula that attempts to measure gerrymandering. For deciding whether this formula works, a few highly relevant mathematical facts were discovered so recently, the Supreme Court probably doesnt know about them. But you will if you attend this talk. No math or political science background will be assumed.

Wesleyan's Undergrad Math Club Presents: Ann Guo Career Engineering 101 Come learn how to design, build, and test careers that will fulfill your passions while considering the limitations imposed by parents, society, and studentloans. Ann is an MIT-trained computer scientist who eventually found her calling as a career coach. In between, she ran global campus recruiting at analgorithmic trading firm where she gained insider knowledge on the hiring process. At Passion Analytics, she is developing an automated online careercoach to help people at scale. Ann holds BS & MEng degrees in Computer Science from MIT and PhD from UMass Amherst. Lunch will be served!
