Simplicial complexes are versatile objects in the intersection of graph theory, combinatorics, topology, and geometry. While mathematicians have always appreciated the fact that simplicial complexes are extremely powerful in spite of being easy to define and relatively easy to work with, their usefulness in real-world applications has increased dramatically just in the last decade or so.In this talk, I will first discuss the definition and the basic constructions that can be performed with simplicial complexes, toggling back and forth between combinatorics and topology. I will then give an overview of some of their recent applications in signal processing, neuroscience, data analysis, and social sciences. I will in particular describe ongoing work by several undergraduates at Wellesley College in which certain types of political systems and their interactions are modeled by simplicial complexes.
This talk should be accessible to anyone who has had some exposure to combinatorics (basics of combinations and permutations).
