A Witt type formula
G. A. T. F. da Costa
This paper investigates some combinatorial and algebraic properties of a Witt type formula for graphs.
Generalized Symmetric Divergence Measures and Metric Spaces
G. A. T. F. da Costa, Inder Jeet Taneja
Recently, Taneja studied two one parameter generalizations of J-divergence, Jensen-Shannon divergence and Arithmetic-Geometric divergence. These two generalizations in particular c…
Feynman Identity: a special case. II
G. A. T. F. da Costa, J. Variane
In this paper, the results of part I regarding a special case of Feynman identity are extended. The sign rule for a path in terms of data encoded by its word and formulas for the n…
Combinatorial formulation of Ising model revisited
G. A. T. F. da Costa, A. L. Maciel
In 1952, Kac and Ward developed a combinatorial formulation for the two dimensional Ising model which is another method of obtaining Onsager's formula for the free energy per site…
