Bicritical graph — бикритический граф.
A finite, undirected, connected and simple graph [math]\displaystyle{ \,G }[/math] is said to be bicritical if [math]\displaystyle{ \,G - u - v }[/math] has a perfect matching for each pair of vertices [math]\displaystyle{ u }[/math] and [math]\displaystyle{ v }[/math] in [math]\displaystyle{ \,G }[/math] such that [math]\displaystyle{ u \neq v }[/math].
Bicritical graphs play a central role in the decomposition theory of graphs in terms of their maximum matchings.
