Title: | Multicomplexes in symplectic topology |

Seminar: | Symplectic Topology Seminar |

Speaker: | David Hurtubise (PSU) |

Abstract: |

TBA
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 within symplectic
topology and have sometimes been confused with spectral
sequences. In this series of talks I will give a survey
of multicomplexes within symplectic topology and explain how
a multicomplex determines at least two different spectral
sequences.
