Title:Multicomplexes and their applications
Seminar:Topology/Geometry Seminar
Speaker:David Hurtubise, Penn State
Abstract:
A multicomplex is a bigraded R-module X_pq with homomorphisms d_i:X_pq ---> X_p-i,q+i-1 such that \sum_{i+j = n} d_i d_j = 0 for all n. A multicomplex can often be assembled to form a chain complex (C,d) where the differential is given by the sum d = d_0 + d_1 +.... A bicomplex is an example of a multicomplex where d_i = 0 for all i > 1. Multicomplexes appear in several contexts in the literature and have sometimes been confused with spectral sequences. In this talk I will give a survey of multicomplexes and their applications.
