On regularization in multiparameter eigenvalue problems

Аннотация

We consider the computation of simple and multiple eigenvalues and the corresponding eigenelements of a multiparameter eigenvalue problem in the sense of Atkinson by the reduction pseudoperturbation method. Namely, we regularize the original operator functions by finite-dimensional linear operators, thus reducing the case of multiple eigenvalues to that of simple ones.
