Multiplicity of nodal solutions for a critical quasilinear equation with symmetry
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
A finite element method for surface diffusion: The parametric case
(Elsevier, 2005-02)
Surface diffusion is a (fourth order highly nonlinear) geometric driven motion of a surface with normal velocity proportional to the surface Laplacian of mean curvature. We present a novel variational formulation for ...
Operador Laplaciano Adaptado para Mallas Hibridas de Triángulos y Cuadrángulos
(2016-01-29)
En las dos últimas décadas los métodos de modelado tridimensional utilizadas por los artistas han ido evolucionando y desarrollándose rápidamente, en parte gracias al uso de operadores vectoriales de geometría diferencial, ...
Critical points of the regular part of the harmonic Green function with Robin boundary condition
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008-09-01)
In this paper we consider the Green function for the Laplacian in a smooth bounded domain Omega subset of R-N with Robin boundary condition
partial derivative G(lambda)/partial derivative nu + lambda b(x)G(lambda) = 0, ...
Extensões auto-adjuntas do operador de Schrödinger magnético em domínios com pouca regularidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2020-02-20)
We find one parametrization of all self-adjoint extensions of the magnetic Schrödinger
operator, in a quasi-convex domain with compact boundary, and magnetic potentials
with low regularity. In this parametrization we use ...
Existência de soluções positivas para o p-Laplaciano com dependência do gradiente
(Universidade Federal de Minas GeraisUFMG, 2010-02-25)
The main aim of this work is to prove the existence of positive solutions for Dirichlet problems involving the p-Laplacian operator and nonlinearities that depend on the gradient of the solution. We will consider the problem ...
Attenuation of reverse time migration artifacts using Laguerre-Gauss filtering
(European Association of Geoscientists and Engineers, EAGE, 2017-06-12)
Low-frequency artifacts appear in seismic images obtained by reverse time migration with the zero-lag crosscorrelation imaging condition due to the unwanted correlation of diving waves, head waves and backscattered waves. ...
The two-dimensional Lazer-McKenna conjecture for an exponential nonlinearity
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-12-01)
We consider the problem of Ambrosetti-Prodi type
[GRAPHICS]
where Q is a bounded, smooth domain in R-2, phi(1) is a positive first eigenfunction of the Laplacian under Dirichlet boundary conditions and h is an element ...
GENERALIZED EUCLIDEAN BOSONIC STRING EQUATIONS
(SPRINGER, 2012)
We consider nonlinear equations of the form p(?)u = U(x, u(x)), in which p is a real-valued function satisfying some suitable technical conditions, and ? stands for the Laplacian operator. We formulate a functional calculus ...
