Given a simplicial complex and a cycle, the minimum bounded chain problem asks to find the smallest chain whose boundary is the given cycle. In this talk we analyze the computational complexity of the minimum bounded chain problem in the special case where the simplicial complex is embedded in Euclidean space. Using duality we rephrase the topological problem as a graph theoretic problem. Assuming some natural conjectures in complexity theory, we show that for all c > 1 there is no polynomial time algorithm yielding a solution less than c times the size of the optimal solution.
Coding theory is the mathematical theory of how to accurately transmit information over noisy channels. For instance, when we receive a message can we detect if there was an error in transmission? If so, can we correct it? In this talk we will recall the basic definitions of (linear) coding theory. Given a linear code, we can associate a lattice, which is where number theory starts to come into the picture. We will discuss how one can use these lattices to associate modular forms to codes and some of the results one can prove using modular forms.
Women in Policy and Women in Science invite all for a talk and discussion on culturally competent mentorship with Dr. Jeff Kenney (Office of Institutional Diversity). Pizza and refreshments provided.

Arthur Mills, a second year Mathematics graduate student, has received funding to attend the Graduate Student Topology and Geometry Conference. This conference is scheduled for April 11th and 12th, at Indiana University in Bloomington, Indiana. See https://gstgc20.sitehost.iu.edu/GSTGC2020Poster.pdf for more information.
There are four Oregon State Mathematics students scheduled to attend the Pacific Northwest Geometry Seminar. The graduate students attending include Arthur Mills, Johannes Krotz, and Zachary Gregg. They will be accompanied by Eli Winkelman, an undergraduate math student. The seminar will take place in Portland on March 7th and 8th. More information about the seminar can be found on the following website: https://sites.math.washington.edu/~lee/PNGS/2020-spring/index.html.
