ABSTRACT
Let â„‹ be a complex seperable Hilbert space and â„’(â„‹ ) denote the collection of bounded linear operators on â„‹ . For an operator in â„’(â„‹ ), rad{ A}' denotes the Jacobson radical of the commutant of A. This paper characterizes the similarity of strongly irreducible operator weighted shift in terms of { A}'/ rad{ A}'. Moreover, we suggest some ways to determine when an operator weighted shift is strongly irreducible and when its commutant is commutative.

Let T( t), t â‰¥ 0, be a C 0-semigroup of linear operators acting in a Hilbert space H with norm |Â·|. We prove that T( t) is uniformly bounded, i.e., | T( t)| â‰¤ M, t â‰¥ 0, if and only if the following condition is satisfied: , where T* is the adjoint operator.

The extended semantic realism (ESR) model proposes a new theoretical perspective which embodies the mathematical formalism of Hilbert space quantum mechanics (QM) into a broader noncontextual, hence local, framework, reinterpreting quantum probabilities as conditional (in a nonstandard sense)....

In terms of abstract boundary conditions, we have established the connection between resolvents of two maximal dissipative extensions of a symmetric operator with arbitrary defect numbers acting in a Hilbert space. In particular, the criterion of resolvent comparability of the operators under...

This work attempts to approximate the resolvent of the algebraic operator, which multiplies it operand by a single independent variable, on the constant subspace of the Hilbert space under consideration. To this end we use the space folding technique which reflects all interactions between the...

In this paper we show that a linear variational inequality over an infinite dimensional real Hilbert space admits solutions for every nonempty bounded closed and convex set, if and only if the linear operator involved in the variational inequality is pseudo-monotone in the sense of Brezis.

In this paper we give some topological conditions which ensure the closedness of the sum and product of two closed linear operators acting in a Hilbert space. We get also a general result on the formula of the adjoint (well known for bounded operators) of the sum and product in the set of...
