Abstract
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
∑k=1∞{μk(σ1,…,σn)+P}−2 as P→∞. Further results may be obtained.
