Andrés David Santamaría-Galvis: What does the h-vector of a simplicial complex know?

Speaker: Andrés David Santamaría-Galvis (IMFM)

Abstract: The h-vector is a fundamental invariant that encodes more subtle information about a simplicial complex than the obvious f-vector. In this talk, I will share a personal perspective on its power, using the framework of partitionability and a picture-loaded style to appeal to the audience's intuition.
