## Abstract In this paper it is shown that an evolution operator is generated by a family of closed linear operators whose common domain is not necessarily dense in the underlying Banach space, under the stability condition proposed by the second author from the viewpoint of finite difference appro

Given a continuous semiring A and a collection α’ of semiring morphisms mapping the elements of A into finite matrices with entries in A we define α’-closed semirings. These are fully rationally closed semirings that are closed under the following operation: each morphism in α’ maps an element of the α’
## Abstract The existence of the wave operators for the selfβadjoint operator constructed by βοΈ~β2~βconstruction is discussed in the abstract theory by using Kato's smooth perturbation method. Moreover, the __s__βmatrix is calculated explicitly.
The connection between the approximation property and certain classes of locally convex spaces associated with the ideal B) of approximable operators will be discussed. It mill be shown that a FRECHET MOXTEL space has the approximation property iff it is a mixed @-space, or equivalently, iff its str
