Abstract:
The asymptotic behavior of solutions to spectral problems for the Laplace operator in a domain with a rapidly oscillating boundary is analyzed. The leading terms of the asymptotic expansions for eigenelements are constructed, and the asymptotics are substantiated for simple eigenvalues.
Key words:
oscillating boundary, spectrum of the Laplacian, asymptotics, matching of asymptotic expansions.
