A Multidirected Hypergraph Representation of Matrices with 0, 1, −1 Entries,
Parts I and II

Abstract for the Combinatorics Seminar
2008 December 9, 16

A multi-directed hypergraph is a combinatorial representation of {0, +1, −1}-matrices that extends the concepts of signed graphs to hypergraphic analogs. I will discuss their discovery and development from hypergraphic matrices and the problems in extending the signed-graphic treatment of the classification of column dependencies.
