, 2014 In the present work, we study properties of some integro-differential operators of the Hadamard-Marchaud type in the class of harmonic functions. As an application of these properties, we consider the question of the solvability of a nonlocal boundary ...

International Journal of Mathematics and Mathematical Sciences, Volume 31, Issue 11, Page 687-694, 2002., 2002 We solve the Dirichlet problem for acoustic scattering from a surface which has been perturbed by the addition of one or more bumps. We build the solution for the bumpy case using the Green′s function for the unperturbed surface, and the solution of a local integral equation in which the integration is carried out only over the added bumps. We conclude

On certain nonlinear elliptic systems with indefinite terms
Electronic Journal of Differential Equations, 2002 We consider an elliptic quasi linear systems with indefinite term on a bounded domain. Under suitable conditions, existence and positivity results for solutions are given. Submitted April 2, 2002. Published October 2, 2002.

A new variable exponent Picone identity and applictions
, 2019 In this paper, we derive a new variable exponent Picone identity for p(x) -Laplacian, which contains some known Picone identities. As applications, a strict monotonicity of principal eigenvalues with respect to domains for the eigenvalue problems to p(x)

A Diagonalized Legendre Rational Spectral Method for Problems on the Whole Line
Journal of Mathematical Study, 2018 A diagonalized Legendre rational spectral method for solving second and fourth order differential equations are proposed. Some Fourier-like Sobolev orthogonal basis functions are constructed which lead to the diagonalization of discrete systems ...
