摘要

We study interpolation properties of the perturbed Sobolev spaces \(H^{s,p}_\alpha \) , associated with singular perturbation \(\Delta _\alpha \) of Laplace operator in Euclidean space of dimensions 2 and 3. The interpolation result implies interpolation inequalities useful in the applications.
