Homological characterizations of planar and projective planar graphs.

In the past, most characterizations of graphs that imbed in a given surface S have been Kuratowski-like forbidden subgraph characterizations; that is, a graph imbeds in S iff the graph does not contain a subdivision of one of a finite list of graphs FS. We will discuss some algebraic characterizations (old and new) of graphs that imbed in the plane or projective plane. These algebraic characterizations are inspired by classical homology theory.
