Branwen Purdy at her stall during OMSI meet-a-scientist day.

Branwen Purdy prepares hands-on activities for kids at the OMSI Meet-A-Scientist Day in Portland, to share hands-on learning experiences about her research in topological data analysis.

Join us for these events hosted by the Department of Mathematics, including colloquia, seminars, graduate student defenses and outreach, or of interest to Mathematicians hosted by other groups on campus.

An introduction to persistent homology transform.

STAG 112
Graduate Student Seminar

Speaker: Zejing Wang

Abstract: Persistent homology transform (PHT) contains richer topological structure of shapes than persistent homology. In this talk, we will start by reviewing backgrounds in persistent homology. Then we will define PHT and prove a result on injectivity that PHT is sufficient to differentiate any shape in $\mathbb{R}^3$. This talk is based on the work by Turner, Mukherjee and Boyer (2014).
