APPLIED AND COMPUTATIONAL MATHEMATICS SEMINAR

**Speaker:** Mason Porter, UCLA Dept. of Mathematics

**Title: ***
Topological Data Analysis of Spatial Complex Systems
*

**Abstract:**
From the venation patterns of leaves to spider webs, roads in cities, and granular materials, the structure of many systems are influenced heavily by space. Accordingly, the analysis of the effects of space on structure and function is an active area in the study of networks and other complex systems. In this talk, I'll give an introduction to topological data analysis (especially persistent homology) and discuss its application to spatial complex systems. As an illustrative example, I will present a case study using apocalyptic voting data from California in 2016.
