The definition of a boolean representation of a matroid and a simplicial complex will be given. A general theory will be outlined including that all matroids have boolean representations and calculating the minimum boolean representations of some classical matroids. Relations with the shellability of a simplicial complexes will be considered. Finally applications to semigroups will be given.

This is current research with Pedro Silva, based on some previous research by Zur Izhakian and the author.
