Necessary and sufficient condition for compactness of the embedding operator
A. G. Ramm
An improvement of the author's result, proved in 1961, concerning necessary and sufficient conditions for the compactness of an imbedding operator is given.
Embedding operators and boundary-value problems for rough domains
V. G. Goldshtein, A. G. Ramm
In the first part of the paper boundary-value problems are considered under weak assumptions on the smoothness of the domains. We assume nothing about smoothness of the boundary $\…
A symmetry problem
A. G. Ramm
The following result is proved: {\bf Theorem.} Let be a bounded domain homeomorphic to a ball, be its volume, be the surface area of its smooth boundary…
On the discrepancy principle
A. G. Ramm
A simple proof of the convergence of the variational regularization, with the regularization parameter, chosen by the discrepancy principle, is given for linear operators under sui…
