Maximal independent sets in graphs with given matching number

Combinatorics 2025-06-02 v2

Abstract

A maximal independent set in a graph GG is an independent set that cannot be extended to a larger independent set by adding any vertex from GG. This paper investigates the problem of determining the maximum number of maximal independent sets in terms of the matching number of a graph. We establish the maximum number of maximal independent sets for general graphs, connected graphs, triangle-free graphs, and connected triangle-free graphs with a given matching number, and characterize the extremal graphs achieving these maxima.
