Boundary Value Problems for a Second-Order Elliptic-Type Operator Differential Equation,We will consider the differential expression..where A is a lower semi-bounded self-adjoint operator, and for any fixed.q(t) is a bounded self-adjoint operator on a Hilbert space n. We assume that the operator-function.is strongly measurable and that.as a function of t, is bounded on .

Boundary Values of Solutions of Differential Equations in a Banach Space,This section is devoted to a brief presentation (mainly without proofs) of some results in the theory of semigroups needed to investigate solutions of operator differential Eqations in a Banach space.

Extensions of Symmetric Operators,e the traditional approach used in the theory of self-adjoint extensions of symmetric operators, in this section we describe the extensions in terms of abstract boundary conditions which are convenient to use in boundary value problems for differential Eqations. In this connection, the notions of a
