Algebra Seminar: Celoria -- Uberhomology of simplicial complexes

Daniele Celoria is speaking in the Algebra Seminar this week.  We will go out for lunch
after the talk.  

When: Friday 19 May, 12-1pm 

Where: Carslaw 173 

Title: Uberhomology of simplicial complexes 

Abstract: We introduce uberhomology, a combinatorially defined homology theory for
simplicial complexes.  After proving some of its properties, we’ll show how a
specialisation is related to connected domination in graphs.  We’ll conclude by proving
that a part of these groups can be described it in terms of the Mayer-Vietoris spectral
sequence.  This is partly a joint work with C.Caputi and C.Collari.
