AN APPLICATION OF CIRCUIT POLYNOMIALS TO THE COUNTING OF SPANNING TREES IN GRAPHSE. J. Farrell and J. C. GrellDepartment of Mathematics, The University of the West Indies, St. Augustine, TrinidadAbstract: $t$ is shown that the number of spanning trees in a graph can be obtained from the circuit polynomial of an associated graph. From this, the number of spanning tress in a regular graph is shown to be obtainable from the characteristic polynomial of a node-deleted subgraph. Finally, Cayley's theorem for the number of labelled tress is derived. Classification (MSC2000): 05C99 Full text of the article:
