Extending Persistent Homology: Zigzags and Well Groups

UC Berkeley Applied Algebra Minisymposium


November 4, 2015
1:00pm to 4:00pm
UC Berkeley


This talk will describe two extensions to persistent homology, zigzag persistent homology and well groups, and how all three relate to each other, through a Mayer--Vietoris pyramid, when the input data is a real-valued function.
