EXISTENCE AND NONEXISTENCE OF GLOBAL POSITIVE SOLUTIONS FOR DEGENERATE PARABOLIC EQUATIONS IN exterior domains
收藏 引用
Acta Mathematica Scientia 2010年 第3期30卷 713-725页
作者: 曾宪忠 刘振海 Department of Mathematics and Computational Science Hunan University of Science and Technology Department of Mathematics Central South University
This article deals with the degenerate parabolic equations in exterior domains and with inhomogeneous Dirichlet boundary conditions. We obtain that pc = (σ + m )n / ( n-σ- 2 ) is its critical exponent provided ... 详细信息

THE LIMITING ABSORPTION METHOD FOR A TRANSMISSION PROBLEM IN ACOUSTIC SCATTERING
收藏 引用
Journal of Partial Differential Equations 2006年 第4期19卷 359-368页
作者: Messaoud SOUILAH Faculté de Mathématiques USTHB Bp 32 El Alia Bab Ezzouar Alger 16111 Algérie
The limiting absorption principle is used to solve the scattering problem of time harmonic acoustic waves by penetrable objects in Sobolev spaces. The method is based on integral representation of the solution using t... 详细信息
