Preference structures, choice functions and their logical form
(2009-02-20)Binary relations and choice functions are two different tools for describing DMpreferences on a finite set of alternatives. Normal choice functions are the link betweenthese two tools. These choice functions are easily ... -
Sobre los números de Hal y Lah
(2009-02-20)In this article we study some properties concerning the Hal (H kn ) and Lah numbers(Lkn ), which are those that arise in the theory of combinatorics in association with the‘upward and downward factorial polynomials’ [x]n ... -

The Determinant of Matching Matrix in the Evaluation of Matching Polynomial
(2011-04-29)A characterization is given for graphs whose matching polynomial is the determinant of their matching matrices. The matching matrix is then modified and its relation with other graph polynomials is examined. -
