[Alta-Logic] Peripatetic Seminar on Tuesday (tomorrow)

[Florian Schwarz]

Dear all,

Tomorrow, on Tuesday, December 10th, Bjørnar Gullikstad Hem (EPFL) will 
speak at the peripatetic seminar. His talk will be streamed at 10 am in 
ICT 616.

Title: Functor calculus for multi-persistent homology

Abstract: Functor calculus is a general framework for studying functors, 
and comes in many flavors. We construct a variant of functor calculus, 
called poset cocalculus, for studying functors out of posets. Our 
motivation is to better understand multi-persistence modules, as these 
modules can be viewed as functors from R^k into a category of chain 
complexes. We demonstrate some properties of poset cocalculus, and apply 
these in concrete examples with multi-persistence modules. We finish by 
giving examples of poset cocalculus in other contexts, such as 
filtrations of simplicial complexes
Hope to see you all there.

Best regards,

Florian Schwarz
