O problema de Dirichlet para a equacão dos gráficos mínimos com dado no bordo lipschitz contínuo
(Universidade Federal de Santa MariaBrasilMatemáticaUFSMPrograma de Pós-Graduação em MatemáticaCentro de Ciências Naturais e Exatas, 2016-12-02)
In this work, we study existence and non existence for the Dirichlet problem for the minimal
graph equation in non convex domains of the plane. We search for conditions on the boundary
data which be the less restricted ...
Zeros de séries de Dirichlet e de funções na classe de Laguerre-Pólya
(Universidade Estadual Paulista (Unesp), 2017-05-11)
Estudamos tópicos relacionados a zeros de séries de Dirichlet e de funções inteiras. Boa parte da tese é voltada à localização de zeros de séries de Dirichlet via critérios de densidade. Estabelecemos o critério de ...
O problema de Dirichlet para a equação das hipersuperfícies mínimas em domínios arbitrários de uma variedade Riemanniana
(Universidade Federal de Santa MariaBrasilMatemáticaUFSMPrograma de Pós-Graduação em MatemáticaCentro de Ciências Naturais e Exatas, 2018-08-22)
In this work we study the Dirichlet problem for the minimal graph equation on C2-domains Ω ⊂ M , where M is an arbitrary complete Riemanniam manifold. We show that, in the case where Ω is bounded, for ϕ ∈ C2(∂Ω), there ...
Weighted a priori estimates for the solution of the Dirichlet problem in polygonal domains in R2
(Michigan State University Press, 2014-01)
Let be a polygonal domain in R2 and let U be a weak solution of u = f in with Dirichlet boundary condition, where f 2 Lp !( ) and ! is a weight in Ap(R2), 1 < p < 1. We give some estimates of the Green function ...
Bohr's absolute convergence problem for Hp-Dirichlet series in banach spaces
(Mathematical Sciences Publishers, 2014-06)
The Bohr-Bohnenblust-Hille theorem states that the width of the strip in the complex plane on which an ordinary Dirichlet series ∑nann-s converges uniformly but not absolutely is less than or equal to 12, and this estimate ...
Dirichlet-to-Neumann Maps on Trees
(Springer, 2019-12)
In this paper we study the Dirichlet-to-Neumann map for solutions to mean value formulas on trees. We give two alternative definition of the Dirichlet-to-Neumann map. For the first definition (that involves the product of ...
Dirichlet Type Problem for 2D Quaternionic Time-Harmonic Maxwell System in Fractal Domains
(2020)
We investigate an electromagnetic Dirichlet type problem for the 2D quaternionic time-harmonic Maxwell system over a great generality of fractal closed type curves, which bound Jordan domains in . The study deals with a ...
