ON THE BOUNDARY STABILIZATION OF WAVE EQUATION WITH VARIABLE COEFFICIENT
Wave equation boundary feedback expone
2007/12/10
摘要 This paper is concerned with the stabilization problem of wave equation with variable coefficient under boundary feedback control. It is shown that the energy of the system decays exponentially if ...
For the variable coefficient elliptic eigenvalue problem on a smooth domain or aconvex polygonal domain,a numerical quadrature scheme over triangles is used for computing the coefficient of the result...
The Ritz projections of the elliptic problem-\partial_i (a_(ij)(\partial _ju)+c_0u=f in Ω, u=0 on \partial Ω,and the quasilinear eiliptic problem-\partial (a_i(x,Du))+a_0(x,Du)=0 in Ω, u=0 on \partial...
