We show that every cubic bridgeless graph G has at least 2|V (G)|/3656 perfect matchings. This confirms an old conjecture of Lov´asz and Plummer.
We obtain the generating functions for partial matchings avoiding neighbor alignments and for partial matchings avoiding neighbor alignments and left nestings. We show that there is a bijection betwee...
A tangled diagram on [n] = {1,..., n} is a labeled graph for which each vertex has degree at most two. The vertices are arranged in increasing order on a horizontal line and the arcs are drawn in the ...
