This paper introduces and systematically investigates the notion of unitary quasi-square equivalence
for bounded linear operators on Hilbert spaces. This equivalence relation, defined through the unitary equivalence
of ...

This paper introduces and studies a novel class of equivalence relations in operator theory, called
deformed-metrically equivalent operators. Two operators S and T in B(H) are said to be deformed-metrically equivalent if ...
This paper introduces and investigates a novel generalization of operator similarity, termed (α, β)–almost similarity,
which extends the concept of almost similar operators by incorporating two real parameters. We establish ...
In this paper, we investigate the local spectral properties of bounded linear operators A and B acting on a
Hilbert space H , which satisfy the generalized operator equation

In ideal situation, road infrastructure projects should be completed within the planned budget, schedule, and
scope to ensure efficient utilization of public resources and timely delivery of transport services that ...
The Furuta inequality and its grand version are cornerstone results in operator theory, providing powerful
relationships between positive operators. While highly general, these classical inequalities are constrained
by ...
This paper introduces and systematically investigates a novel class of operators called fuzzy soft prenormal
operators (FSP) within the framework of fuzzy soft Hilbert spaces. Motivated by the need to extend classical
operator ...

Aims: To introduce and investigate a new generalized family of integral operators for analytic functions in the open unit
disk, which unifies and extends several known operators by incorporating multiple functions and ...
We formulate a population-density-dependent migration of a predator and prey between two patches. The
migration is influenced by prey and predator densities such that when the predator population is huge, the
migration ...

Arid and Semi-Arid Landscapes (ASALs) support a substantial portion of the world's population and multiple
ecological and social functions. However, landcover outcomes in ASALs are determined by competing land uses,
which ...

Introduction: While Flueggea virosa (Roxb. Ex Willd.) Royle root bark is
traditionally used in several parts of East Africa for fertility regulation, its
contraceptive potential has not been systematically investigated. ...

Habitat loss and degradation pose significant threats to biodiversity, especially in tropical regions characterized
by high biodiversity levels and elevated deforestation rates. However, there is a lack of sufficient ...
