Radonification of Cylindrical Semimartingales by a Single Hilbert Schmidt Operator
نویسندگان
چکیده
It is proved that in Hilbert spaces a single Hilbert–Schmidt operator radonifies cylindrical semimartingales to strong semimartingales. This improves a result due to Badrikian and¨Ustünel (also L. Schwartz), who needed composition of three Hilbert–Schmidt operators.

G-frames and Hilbert-Schmidt operators
In this paper we introduce and study Besselian $g$-frames. We show that the kernel of associated synthesis operator for a Besselian $g$-frame is finite dimensional. We also introduce $alpha$-dual of a $g$-frame and we get some results when we use the Hilbert-Schmidt norm for the members of a $g$-frame in a finite dimensional Hilbert space.
متن کاملUniformly Γ ––radonifying Families of Operators and the Stochastic Weiss Conjecture
We introduce the notion of uniform γ –radonification of a family of operators, which unifies the notions of R–boundedness of a family of operators and γ –radonification of an individual operator. We study the properties of uniformly γ –radonifying families of operators in detail and apply our results to the stochastic abstract Cauchy problem dU(t) = AU(t)dt +BdW (t), U(0) = 0. Here, A is the ge...

We prove the following statements about bounded linear operators on a separable, complex Hilbert space: (1) Every normal operator N that is similar to a Hilbert-Schmidt perturbation of a diagonal operator D is unitarily equivalent to a Hilbert-Schmidt perturbation of D; (2) For every normal operator A', diagonal operator D and bounded operator X, the Hilbert-Schmidt norms (finite or infinite) o...
متن کاملStochastic differential inclusions of semimonotone type in Hilbert spaces
In this paper, we study the existence of generalized solutions for the infinite dimensional nonlinear stochastic differential inclusions $dx(t) in F(t,x(t))dt +G(t,x(t))dW_t$ in which the multifunction $F$ is semimonotone and hemicontinuous and the operator-valued multifunction $G$ satisfies a Lipschitz condition. We define the It^{o} stochastic integral of operator set-valued stochastic pr...
