In this comprehensive study, we delve deeply into the concept of multivariate total positivity, defining it in accordance with a direction. We rigorously explore numerous salient properties, shedding light on the nuances that characterize this notion

In this paper, we define a multivariate order based on the concept of orthant directional dependence and study some of its properties. The relationships with other dependence orders given in the literature are also studied. We analyze the order betwe

In this paper we find pointwise best-possible bounds on the set of copulas with a given value of the Spearman's footrule coefficient. We show that the lower bound is always a copula but, unlike the bounds on sets of copulas with a given value of othe

We study conditions on sets in order to be zero-sets of semi-copulas, quasi-copulas, and with special attention, of copulas. We find necessary and sufficient conditions for characterizing the zero-sets of absolutely continuous copulas and copulas who

We propose a definition of conditional expectation in a finitely additive setting by relying on the theory of charges and circumventing the lack of an exact Radon–Nikodym theorem in this setting. We also show that the definition we propose satisfie

We give a new approach to Taylor's remainder formula, via a generalization of Cauchy's generalized mean value theorem, which allows us to include the well-known Schölomilch, Lebesgue, Cauchy, and the Euler classic types, as particular cases.

We introduce and study representation systems for the numbers in the unit interval [0, 1]. We call them ϕ m -systems (where ϕ m is a pseudo-golden ratio). With the aid of these representation systems, we define a family h m of strong negations and
