title: Ground state entropy of the Potts antiferromagnet on homeomorphic expansions of kagomé lattice strips.
abstract: We present exact calculations of the chromatic polynomial and resultant ground state entropy of the q-state Potts antiferromagnet on lattice strips that are homeomorphic expansions of a strip of the kagomé lattice. The dependence of the ground state entropy on the form of homeomorphic expansion is elucidated.
