Spectral analysis of certain groups of isometries on Hardy and Bergman spaces
(Academic Press, 2017-12-15)
Using the similarity theory of semigroups as well as spectral theory, we obtain the resolvents of the generators of strongly continuous groups of isometries on the Hardy and Bergman spaces. These groups are obtained as ...
Some Properties of the Essential Numerical Range on Banach Spaces
(HIKARI Ltd,, 2017)
We study the properties of the essential algebraic numerical range as
well as the essential spatial numerical range for Banach space operators.

On the maximal numerical range of elementary operators
(Academic Publications, Ltd., 2017-02)
The notion of the numerical range has been generalized in different directions.
One such direction, is the maximal numerical range introduced by Stampfli (1970) to derive
an identity for the norm of a derivation on L(H). ...
On the Numerical Range of a Generalized Derivation
(HIKARI Ltd,, 2017)
We examine the relationship between the numerical range of the
restriction of a generalized derivation to a norm ideal J and that of its
implementing elements.

Recursive Relation for Zero In ated Poisson Mixture Distributions
(2017)
The paper extends the work of Sarguta who derived recursive re- lations for univariate distributions by considering the ZIP continuous mixtures. The paper gives a recursive formular which can be used to evaluate the mixed ...
Provable, Secure & Democratic Election Model
(INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY SCIENCES AND ENGINEERING, 2017)
Democracy is founded on the principle of elections and
opinion expression capabilities. Bimber & Leggewie foresaw
e-democracy. Voting is an information transfer model. Trust is
essential to communication channel but ...
