Eigenvalues of the negative Laplacian for arbitrary multiply connected domains
Elsayed M. E. Zayed · International Journal of Mathematics and Mathematical Sciences · 1995
The purpose of this paper is to derive some interesting asymptotic formulae for spectra of arbitrary multiply connected bounded domains in two or three dimensions, linked with variation of positive distinct functions entering the boundary conditions, using the spectral function as P → ∞. Further results may be obtained.
