A classical result of Erdos and Gallai determines the maximum size m(n,?)m(n,\nu) of a graph GG of order nn and matching number ?n\nu n. We show that GG has factorially many maximum matchings provided that its size is sufficiently close to m(n,?)m(n,\nu).

As a natural variant of domination in graphs, Dankelmann et al. [Domination with exponential decay, Discrete Math. 309 (2009) 5877-5883] introduced exponential domination, where vertices are considered to have some dominating power that decreases exponent... see more
