A posteriori estimates for problems with monotone operators
Vladimir Bobkov, Svetlana Pastukhova
We propose a method of obtaining a posteriori estimates which does not use the duality theory and which applies to variational inequalities with monotone operators, without assumin…

On resolvent approximations of elliptic differential operators with locally periodic coefficients
Svetlana Pastukhova
We study the asymptotic behaviour, as the small parameter tends to zero, of the resolvents of uniformly elliptic second-order differential operators with locally peri…

On resolvent approximations of elliptic differential operators with periodic coefficients
Svetlana Pastukhova
We study resolvent approximations for elliptic differential nonselfadjoint operators with periodic coefficients in the limit of the small period. The class of operators covered by…
