I show that continuous convex preference relations that have affine indifference curves do not have a concave representation if there are two indifference curves that are not parallel. In other words a preference relation ...

El propósito del presente trabajo fue identificar los registros semióticos de representación en el tratamiento del crecimiento y concavidad de una función en relación a la función derivada. Se tomaron como objeto de estudio ...

In this paper we consider strictly convex monotone continuous complete preorderings on R+n that are locally representable by a concave utility function. By Alexandroff 's (1939) theorem, this function is twice dífferentiable ...

Distributed hydrological models rely on a spatial discretization composed of homogeneous units representing different areas within the catchment. Hydrological Response Units (HRUs) typically form the basis of such a ...

Concavifiable preferences are representable by a function which is twice differentiable almost everywhere, by theorem of Alexandroff [Alexandroff, A.D., 1939. Almost Everywhere Existence of Second Differentials of Convex ...

En esta tesis se analizan dificultades presentadas por estudiantes de Cálculo I, asignatura del primer año de las carreras de Ingeniería en Recursos Hídricos, Ingeniería Ambiental e Ingeniería en Informática, de la Facultad ...
