On principal eigenpairs for the (p,q)-Laplacian in exterior domain
Maya Chhetri, Pavel Drabek, Ratnasingham Shivaji
We consider an eigenvalue problem of the form \begin{equation*} \left\{\begin{array}{rclll} -Δ_{p} u -Δ_{q} u&=& λK(x)|u|^{p-2}u & \mbox{ in } Ω^e u&=&0\qquad \quad &\mbox{ on } \p…

On the Convergence of the Variational Iteration Method for Klein-Gordon Problems with Variable Coefficients II
Pavel Drabek, Stephen B Robinson, Shohreh Gholizadeh Siahmazgi
In this paper we investigate convergence for the Variational Iteration Method (VIM) which was introduced and described in \cite{He0},\cite{He1}, \cite{He2}, and \cite{He3}. We prov…

Reverse Faber-Krahn and Szego-Weinberger type inequalities for annular domains under Robin-Neumann boundary conditions
T. V. Anoop, Vladimir Bobkov, Pavel Drabek
Let be the -th eigenvalue of the Laplace operator in a bounded domain of the form under the Neumann boundary condition on…
