(SPRINGER, 2008-09)Interpolation inequalities of Gagliardo-Nirenberg type and compactness results for self-adjoint trace-class operators with finite kinetic energy are established. Applying these results to the minimization of various free ...

(2013)In this article we study various convergence results for a class of nonlinear fractional heat equations of the form ⎧⎨ ⎩ ut(t, x)− I[u(t, ·)](x) = f(t, x), (t, x) ∈ (0, T) × Rn, u(0, x) = u0(x), x∈ Rn, where I is a ...

(Universidad de Chile, 2021)La educación es uno de los pilares fundamentales en la construcción de una sociedad moderna, y es necesaria una constante adaptación de las metodologías de enseñanza, en particular, la introducción de nuevas herramientas ...
-
(Universidad de Chile, 2017)En el sistema de educación superior en Chile, la educación matemática y los profesores de institutos profesionales y centros de formación técnica son poco observados. Considerando la influencia de la asignatura matemática ...

Existence and nonexistence of positive solutions to some fully nonlinear equation in one dimension (Academic Press Inc., 2018)In this paper, we consider the existence (and nonexistence) of solutions to −Mλ,Λ ±(u″)+V(x)u=f(u)inR where Mλ,Λ + and Mλ,Λ − denote the Pucci operators with 0<λ≤Λ<∞ V(x) is a bounded function, f(s) is a continuous ...

(Society for Industrial and Applied Mathematics, 2013)In this paper we study the large-time behavior of solutions of one-dimensional fractional Fisher-KPP reaction-diffusion equations, when the initial condition is asymptotically frontlike and it decays at infinity more ...
-
(Elsevier, 2011)In this article we study basic properties for a class of nonlinear integral operators related to their fundamental solutions. Our goal is to establish Liouville type theorems: non-existence theorems for positive entire ...
-
(ELSEVIER, 2010)We study the existence of positive radially symmetric solutions to a class of nonlinear elliptic problems involving extremal operators and nonlinearity of exponential or polynomial type. According to the values of a ...
-
(IOP PUBLISHING LTD, 2013-04-15)In this article we study the existence and asymptotic profiles of high-energy rotation type solutions of the singularly perturbed forced pendulum equation ε2u ε + sin uε = ε2α(t)uε in (−L, L). We prove that the ...

High frequency solutions for the singularly-perturbed one-dimensional nonlinear Schrodinger equation (SPRINGER, 2006-10)This article is devoted to the nonlinear Schrodinger equation epsilon(2)u'' - V(x)u + vertical bar u vertical bar(p-1)u = 0, when the parameter epsilon approaches zero. All possible asymptotic behaviors of bounded ...
-
(CAMBRIDGE UNIV PRESS, 2006-04)In this article we study the asymptotic dynamics of highly oscillatory solutions for the unbalanced Allen-Cahn equation with a slowly varying coefficient. We describe the underlying structure of these solutions through a ...
-
(Universidad de Chile, 2020)Este trabajo consiste en una combinación de dos estudio, entre los cuales se busca responder la pregunta ¿Qué impactos tienen las paralizaciones (o paros) en el aprendizaje de los estudiantes de ingenierías y ciencias? ...
-
(Springer New York LLC, 2018)In this article we are interested in interior regularity results for the solution μ∈∈ C(Ω¯) of the Dirichlet problem {μ=0inΩc,I∈(μ)=f∈inΩ where Ω is a bounded, open set and f∈∈ C(Ω¯) for all є ∈ (0, 1). For some σ ∈ (0, ...

(Elsevier Masson SAS, 1998)In this paper we consider the study of standing wave solutions for a nonlinear Schrödinger equation. This problem reduces to that of finding nonnegative solutions of ε2Δu - V (x) u + (Latin small letter esh) (u) = 0 in Ω. ...
