摘要:
AbstractUsing some imbedding theorems, the Langenbach variational theorem for operator equationPu=f* is obtained as a natural consequence of the Kerner‐Vainberg potentiality theorem coupled with standard results of the variational calculus; in our approach operatorPis defined not over all the spaceXbut only on a dense subspace (compare with [1], pp. 33–34, propositions 3.2 and 3

摘要:
AbstractSymmetry‐ and selfadjointness‐conditions are derived for ordinary differential‐integral‐interface operators under integral‐interface conditions. Criteria for the existence of selfadjoint extensions inL n2×L n2are given. These extensions are characterized in a constructive way. The main tools are some extension‐theorems for linear relations (subspaces), wich are develo

摘要:
AbstractWe are concerned with convex operators mapping a convex subset of a certain topological vector space into an ordered topological vector space, whose positive cone is assumed to be normal. Under the appropriate topological assumptions, we prove the equicontinuity of every pointwise bounded family of continuous convex operators as well as the continuity of every closed convex operator at every algebraically interior point of the domain. We also show that some weak kind of monotonicity implies the continuity of a convex operator.
