Abstract

A new proof of the following fact is proposed. The eigenvalues of the Laplace-Dirichlet operator are continuous as functions in the corresponding space in domains satisfying the uniform cone condition. The author’s approach to this problem is based on a topological version of the upper (lower) limit for sequences of sets.
