G-Topological Groupoids, Osman Mucuk

Turkish Journal of Mathematics

In the groupoid theory, it is unclear that a topological groupoid's quotient groupoid with the quotient topology is topological.  In this paper, we approach this problem considering  G-methods and G-convergence. We define  G-topological groupoid, which agrees with the sequential version of a topological groupoid in the particular case G=lim, and give some counterexamples. Then, we extend the usual properties of topological groupoids to the G-topological groupoids. We also prove that a G-topological groupoid's quotient groupoid is  G-topological groupoid when a normal subgroupoid is suitably chosen. This result enables us to obtain examples of topological quotient groupoids in a particular case.

On Almost Kenmotsu Manifolds Admitting Nearly Vacuum Static Equations With Applications, Uday Chand De, Krishnendu De, Sudhakar Kumar Chaubey

Turkish Journal of Mathematics

In this article, we study certain characteristics of nearly vacuum static equations on almost Kenmotsu manifolds. It is established that an η-Einstein almost Kenmotsu manifold allowing nearly vacuum static equations is of constant scalar curvature and either the solution is trivial or, the manifold reduces to an Einstein manifold. Next,  nearly vacuum static equations on (κ,μ)-almost Kenmotsu manifolds and generalized (κ,μ)'-nullity distribution are considered and we obtain several interesting results. Moreover, we illustrate that if a 3-dimensional Kenmotsu manifold allows nearly vacuum static equations, then the manifold is locally isometric to the hyperbolic space Η3(-1).

Prevalence Of Intimacy Satisfaction In Relation To Burnout And Trauma Saturation Of First Responders, Krystoffer L. Bowman

Doctoral Dissertations and Projects

A shared understanding of this issue enables us to recognize the uniqueness of each individual’s experience, supported by the consistent commitment of trauma-saturated professionals. But what happens when these individuals become so accustomed to trauma that they can no longer recognize it as such? When their professional identity is inherently tied to continuous exposure to trauma, they may unconsciously adopt emotional distancing as a coping mechanism, which can appear to others as a fixed personality trait or lifestyle, even outside the workplace. This professional emotional distancing, often a consequence of growing burnout and trauma saturation, may negatively impact intimacy satisfaction. …
