The factorization properties of operator algebras in separable Hilbert spaces was developed by John von Neumann in collaboration with F.J. Murray in four outstanding papers published from 1936 to 1943. Unfortunately, probably because of conceptual difficulties with physical interpretations, some relevant results presented in those papers, in particular the remarkable examples of factors, have n...

the theory of c-frames and c-bessel mappings are the generalizationsof the theory of frames and bessel sequences. in this paper, weobtain several equivalent conditions for dual of c-bessel mappings.we show that for a c-bessel mapping $f$, a retrievalformula with respect to a c-bessel mapping $g$ is satisfied if andonly if $g$ is sum of the canonical dual of $f$ with a c-besselmapping which  wea...

A space is a Bake space if the intersection of countably many dense open sets is dense. We show that if X is a non-separable completely met&able linear space (pathconnected abelian topological group) then X contains two linear subspaces (subgroups) E and F such that both E and F are Baire but E x F is not. If X is a completely met&able linear space of weight K, then X is the direct sum E@F of t...

This work is devoted to the study of analytic wormhole solutions within framework f ( R ) $f(R)$ gravity theory. To check possibility having structures satisfying energy conditions, by means class I approach pair { Φ r , b } $\lbrace \Phi (r), b(r)\rbrace$ describing geometry has been obtained. Then, in conjunction with a remarkably model, satisfaction null and weak conditions at throat its nei...

Let H be a separable real Hilbert space and let F = (Ft)t∈[0,T ] be the augmented filtration generated by an H-cylindrical Brownian motion (WH(t))t∈[0,T ] on a probability space (Ω,F ,P). We prove that if E is a UMD Banach space, 1 ≤ p < ∞, and F ∈ D(Ω;E) is FT -measurable, then F = E(F ) + ∫ T 0 PF(DF ) dWH , where D is the Malliavin derivative of F and PF is the projection onto the F-adapted ...

The purpose of this paper is to introduce the concept of pairwise F-closedness in bitopological spaces. This space contains both of pairwise strongcompactness and pairwise S-closedness and contained in pairwise quasi H-closedness. The characteristics and relationships concerning this new class of spaces with other corresponding types are established. Moreover, several of its basic and important...

We consider the Fock-Sobolev space F p,m consisting of entire functions f such that f , the m-th order derivative of f , is in the Fock space F . We show that an entire function f is in F p,m if and only if the function zf(z) is in F . We also characterize the Carleson measures for the spaces F , establish the boundedness of the weighted Fock projection on appropriate L spaces, identify the Ban...

In a fuzzy metric space (X;M; *), where * is a continuous t-norm,a locally fuzzy contraction mapping is de ned. It is proved that any locally fuzzy contraction mapping is a global fuzzy contractive. Also, if f satis es the locally fuzzy contractivity condition then it satis es the global fuzzy contrac-tivity condition.
