A Note on the Chebyshev Set Problem in Normed Linear Spaces

Samson Owiti, Benard Okelo, Julia Owino

Best approximation (BA) is an interesting field in functional analysis that has attracted a lot of attention from many researchers for a very long period of time up-to-date. Of gre…

On Monopole Bundle Systems of Complex Hypermanifolds for Composition Operators

Benard Okelo, Jeffar Oburu

In this paper, we give new characterizations of monopole bundle systems of complex hypermanifolds in -dimensional spaces for certain classes of operators. In particular, we cons…

A Note on Approximations of Fixed Points for Nonexpansive Mappings in Norm-attainable Classes

Benard Okelo

Let be an infinite dimensional, reflexive, separable Hilbert space and the class of all norm-attainble operators on In this note, we study an implicit scheme for a…

Norm Inequalities for Inner Product Type Integral Transformers

Benard Okelo

In this paper, we give a detailed survey on norm inequalities for inner product type integral transformers. We first consider unitarily invariant norms and operator valued function…

Characterization of Absolutely Norm Attaining Compact Hyponormal Operators

Benard Okelo

In this paper, we characterize absolute norm-attainability for compact hyponormal operators. We give necessary and sufficient conditions for a bounded linear compact hyponormal ope…

On Certain Conditions for Convex Optimization in Hilbert Spaces

Benard Okelo

In this paper convex optimization techniques are employed for convex optimization problems in infinite dimensional Hilbert spaces. A first order optimality condition is given. Let…
