The concept of exponential function in the context of Vergnaud Theory
(Maryland Institute of Research, 2013-11)
In order to teach exponential functions as well as to study the process of conceptualization through Vergnaud Theory of Conceptual Fields, a didactic sequence was designed. The sequence was tested with four groups of ...
Descripción dinámica de la dispersión por un potencial
(Revista Mexicana de Física, 2009)
Context-dependent functional dispersion across similar ranges of trait space covered by intertidal rocky shore communities
(2017)
Functional diversity is intimately linked with community assembly processes, but its large-scale patterns of variation are often not well understood. Here, we investigated the spatiotemporal changes in multiple trait ...
Invariance of a Shift-Invariant Space in Several Variables
(Springer, 2011-12)
In this article we study invariance properties of shift-invariant spaces in higher dimensions. We state and prove several necessary and sufficient conditions for a shift-invariant space to be invariant under a given closed ...
Extra Invariance of a Shift-Invariant Space in LCA Groups
(Elsevier, 2010-10)
This article generalizes recent results in the extra invariance for shift-invariant spaces to the context of LCA groups. Let G be a locally compact abelian (LCA) group and K a closed subgroup of G. A closed subspace of ...
Rango de una función
(Colombia., 18-12-30)
Para poder clasificar las funciones es necesario definir el rango. El rango de una función es el conjunto formado por todos aquellos elementos del codominio que son imagen de al menos un elemento del dominio, el rango es ...
