In this paper, we explore the intricate connection between orthogonal polynomials and norm
attainable operators within a Hilbert space. We give examples of this relationship by …

Approximations of fixed points have been done in different space and classes. However,
characterizations in normattainable classes remains interesting. This paper discusses …

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 greatest …

The fundamental mathematical problem that remains unsolved is the generalization of
maximality chain conditions for chains of homomorphisms in topological spaces. We give …

Let $ H $ be a reflexive, dense, separable, infinite dimensional complex Hilbert space and
let $ B (H) $ be the algebra of all bounded linear operators on $ H $. In this paper, we carry …

In this note, we provide detailed characterization of operators in terms of norm-attainability
and norm estimates in Banach algebras. In particular, we establish the necessary and …

Orthogonality of operators in Hilbert spaces is a notion that has been studied for a duration
of some time by many mathematicians such as Oleche, Okelo, Agure and many others …
