Abstract Given a finite set of independent random variables, assume one can observe their sum, and denote with s its value. Efron in 1965, Lehmann 1966, described conditions on the involved variables such that each them stochastically increases value , i.e., expected any non-decreasing function variable as increases. In this paper, we investigate stochastic monotonicity property is satisfied wh...

This thesis explores two specific topics of discrete geometry, the multitriangulations and the polytopal realizations of products, whose connection is the problem of finding polytopal realizations of a given combinatorial structure. A k-triangulation is a maximal set of chords of the convex n-gon such that no k+1 of them mutually cross. We propose a combinatorial and geometric study of multitri...
