Abstract

We compute the partition function of the Potts model with arbitrary values of qq and temperature on some strip lattices. We consider strips of width Ly=2L_y=2, for three different lattices: square, diced and `shortest-path' (to be defined in the text). We also get the exact solution for strips of the Kagome lattice for widths Ly=2,3,4,5L_y=2,3,4,5. As further examples we consider two lattices with different type of regular symmetry: a strip with alternating layers of width Ly=3L_y=3 and Ly=m+2L_y=m+2, and a strip with variable width. Finally we make some remarks on the Fisher zeros for the Kagome lattice and their large q-limit.
