In this paper the least-squares mixed finite element is considered for solving secondorder elliptic problems in two dimensional domains. The primary solution u
This paper is conceed with the second order elliptic problems with small periodic coefficients on a bounded domain with a curved boundary. A two-scale curved el
We give some formulae for calculation of the expansions for (1) composition of step-transition operators (STO) of any two difference schemes (DS) for ODE’s, (2
