## Abstract Let __m__(__G__) denote the number of maximal independent sets of vertices in a graph __G__ and let __c__(__n__,__r__) be the maximum value of __m__(__G__) over all connected graphs with __n__ vertices and at most __r__ cycles. A theorem of Griggs, Grinstead, and Guichard gives a formul

Abstract
We find the maximum number of maximal independent sets in two families
of graphs. The first family consists of all graphs with n vertices and at most r cycles. The second family is all graphs of the first family which are connected and satisfy nββ₯β3__r__. Β© 2006 Wiley Periodicals, Inc. J Graph Theory 53: 270β282, 2006

## Abstract We obtain lower bounds on the size of a maximum matching in a graph satisfying the condition |__N(X)__| β₯ __s__ for every independent set __X__ of __m__ vertices, thus generalizing results of Faudree, Gould, Jacobson, and Schelp for the case __m__ = 2.
