Pseudoperturbation operator in generalized eigenvalue problem under group symmetry
B. V. Loginov1, O. V. Makeeva2
| Annotation | It is suggested process for pseudoperturbation operator construction when an considered generalized eigenvalue problem process an group symmetry. On the base of introducing such operator iterational processes {\cite{loginovb2En}-\cite{loginovb3En}} can be applied for refining of approximations to spectral characteristics of direct and conjugate problems. |
