Matematica. 2003, nr. 2(42), pp. 95-112. ISSN 1024-7696.1024-7696https://msuir.usm.md/handle/123456789/9020We study the behavior of solutions of the problem εu′′(t)+u′(t)+Au(t) =f (t), u(0) = u0, u′(0) = u1 in the Hilbert space H as ε → 0, where A is a linear,symmetric, strong positive operator.ensingular perturbationsparabolic equationhyperbolic equationboundary functionArticle
