Cluj polynomials are defined on the unsymmetric Cluj matrices or by a cutting procedure, as the counting polynomials which collect the vertex proximities in the graph. On these proximities, two Cluj polynomials CJS and CJP and the PIv polynomial can be defined. Formulas for these counting polynomials are derived in case of tori of several tessellation.
Keywords: Cluj polynomial, counting polynomial, torus
