Error Estimates in Elliptic Boundary Value Problems, boundary value problems. Because of the limited time, I shall restrict my attention to the Dirichlet problem, although some of the methods are easily carried over to other boundary conditions. The first part will be devoted to second order problems. In fact, in order to illustrate the methods, I wi

On the Existence of an Iterative Method for the Solution of Elliptic Difference Equations with an Ierature. In this paper it will be shown that for rather general domains in the plane there exists an iterative method with work estimates which are better than those now available. This is an abstract existence theorem, not a complete specification of an improved iterative procedure..On a rectangle

The operator T is said to be semibounded (below), if σ (T) has a finite lower bound; in this case we denote by ν(T) and μ (T) the greatest lower bound of σ(T) and σ. (T) respectively, so t

Contintent Equations and Boundary Value Problems,d to the optimal control theory. Our aim is to show that the technique of the contingent equations is useful in the theory of continuous and discrete boundary value problems too. In section 1 we start wtih a new topological method which permits to establish the existence of solutions provided a crit
