Algorithms to count perfect matchings in near planar graphs

It is well known that counting perfect matchings is tractable in planar graphs (due to Kastelyn). I am interested in classes of (for lack of a better word) "near" planar graphs (1-planar, bounded genu …

Generalizations of a theorem of Edmonds/Tutte on existence of a perfect matching in a graphs

It is well known that for a bipartite graph $G$ with bi-adjacency matrix $A$, then $\det A \neq 0$ (as a polynomial) iff $G$ has a perfect matching (there is a similar result for general graphs with T …
