On well-posedness of the nonlocal boundary value problem for parabolic difference equations. (English) Zbl 1077.39015
In an arbitrary Banach space, the authors consider a nonlocal boundary value problem for the difference equation $$\frac{u_k - u_{k-1}}{\tau} + A u_k = \varphi_k, \ 1 \le k \le N, \ N\tau = 1, \ u_0 = u_{[\lambda/\tau]} + \varphi, \tag 1$$ where $A$ is a strongly positive operator. Stability and coercive stability of (1) in various Banach spaces are studied. As applications, difference schemes of boundary-value problems for parabolic equations are considered.
