Abstract
In this paper, we study new classes of operators on separable Banach spaces which are called extended-cyclic operators and extended-transitive operators. We study some properties of their vectors which are called extended-cyclic vectors. We show that if is an extended-cyclic vector for , then is also an extended-cyclic vector for for all . Then, we show the extended-cyclicity is preserved under qsuasi-similarity. Moreover, we prove that an operator is extended-cyclic if and only if it is extended-transitive. As a consequence, the set of all extended-cyclic vectors is a dense and set. Finally, we find some spectral properties of these operators. Particularly, the point spectrum of the adjoint of an extended-cyclic operator has at most one element of modules greater than one. Moreover, if the spectrum of an operator has a connected component subset of , then is not extended-cyclic.
Key Words: Extended-Cyclic, Banach spaces, G_δ set.

Abstract
Let R be a ring with 1 and D be unitary left Module over R. In this paper, we present purely semi small compressible Modules. Also, we give remarks and examples, many properties of such Modules are investigated.
Key Words:
Semi small Submodule, prime Modules, pure Modules, semi small compressible Module.
