Aperfeiçoamento de modelos numéricos para estimativa de propriedades térmicas do solo
(Universidade Federal de Santa Maria, 2019-09-02)
Understanding the soil thermal properties, in particular, diffusivity , volumetric capacity and conductivity is important in applications of several related areas, mainly soil-plant-atmosphere interaction. Studies to ...
Sobre uma classe de problemas elípticos envolvendo o operador p-Laplaciano, com peso e potencial indefinidos e diferentes condições de fronteira
(Universidade Federal de Santa Maria, 2019-03-12)
This work is dedicated to study two distinct classes of eigenvalue problems, involvinthe p-laplacian operator and indefinite weight and potential functions. We give somge
necessary and sufficient conditions such that there ...
Problemas de autovalores para o p-Laplaciano com distintas condições de fronteira
(Universidade Federal de Santa Maria, 2019-07-25)
The goal of this work is to obtain, through the Ljusternik-Schnirelman principle,
a sequence of eigenvalues for p-Laplacian with Dirichlet, Neumann and Robin-Steklov
boundary conditions, the last one which is a combination ...
Multiplicidade de soluções para um problema envolvendo o operador p-laplaciano fracionário
(Universidade Federal de Santa Maria, 2019-02-22)
The aim of the work is to give, through variational methods, sufficient conditions on a
positive parameter to ensure the existence and multiplicity of solutions for the class of
elliptic problems. Such class of problems ...
