T=0 Partition Functions for Potts Antiferromagnets on Moebius Strips and Effects of Graph Topology
We present exact calculations of the zero-temperature partition function of
the -state Potts antiferromagnet (equivalently the chromatic polynomial) for
Moebius strips, with width or 3, of regular lattices and homeomorphic
expansions thereof. These are compared with the corresponding partition
functions for strip graphs with (untwisted) periodic longitudinal boundary
conditions.Comment: 9 pages, Latex, Phys. Lett. A, in pres
