Abstract:

In this paper, it is proved that on a generalized (k,?)'-almost Kenmotsu manifold M2n+1 of dimension 2n + 1, n > 1, the conditions of local symmetry, semi-symmetry, pseudo-symmetry and quasi weak-symmetry are equivalent and this is also equivalent to that M2n+1 is locally isometric to either the hyperbolic space H2n+1(-1) or the Riemannian product Hn+1(-4)xRn. Moreover, we also prove that a generalized (k,?)-almost Kenmotsu manifold of dimension 2n + 1, n > 1, is pseudo-symmetric if and only if it is locally isometric to the hyperbolic space H2n+1(-1).

Abstract:

The aim of this paper is to introduce and study a new class of normal spaces, called epi pi-normal spaces, which lies between epi-normal and epi-almost normal spaces, and epi-normal and epi-quasi normal spaces. Interrelation among some existing variants of normal spaces is discussed and characterizations of epi pi-normal space with some existing variants of normal spaces are obtained. We also proved that epi pi-normal space is a topological property and it is a hereditary property with respect to closed domain subspace. We also investigate the relationships among epi -normal spaces with other

Abstract:

This paper is concerned with the quantum-mechanical decay of a Schwarzschild-like black hole, formed by gravitational collapse, into almost-flat space–time and weak radiation at a very late time. We evaluate quantum amplitudes (not just probabilities) for transitions from initial to final states. This quantum description shows that no information is lost in collapse to a black hole. Boundary data for the gravitational field and (in this paper) a scalar field are posed on an initial space-like hypersurface ΣI and a final surface ΣF. These asymptotically flat three-surfaces are separated by a Lo

Abstract:

Context. Distant trans-Neptunian objects are subject to planetary perturbations and galactic tides. The former decrease with the distance, while the latter increase. In the intermediate regime where they have the same order of magnitude (the “inert Oort cloud”), both are weak, resulting in very long evolution timescales. To date, three observed objects can be considered to belong to this category. Aims. We aim to provide a clear understanding of where this transition occurs, and to characterise the long-term dynamics of small bodies in the intermediate regime: relevant resonances, chaotic zone

Abstract:

The Apliki copper deposit, in the Troodos ophiolite complex of Cyprus, is part of the Skouriotissa mining district. Mining activity at Apliki has resulted in the production of 1,650,000 tons of copper ore. The mineralization is hosted within the sequence of Lower Pillow Lavas of the Troodos ophiolite complex in the western part of the Solea graben. Plagioclase, pyroxenes (augite), magnetite and ilmenite, and rarely olivine are the main magmatic mineral components. The prevailing secondary minerals are celadonite, calcite, analcime and quartz which occur within amygdules or are dispersed within

Abstract:

Purpose Teaching and learning processes are conducted formally in a classroom as the main learning space for schooling system, where it should be implemented effectively to achieve a desired level of satisfaction and comfort for the students. To encourage and sustain students’ motivation for continuous learning, specifically at secondary school level, classroom capacity is increasing significantly. The purpose of this paper is to analyse the guidelines and regulations of building design standard compliance, specifically for classrooms, and suggest the suitability of classroom capacity based on

Abstract:

In this paper, we introduce new forms of continuity, namely, weakly θs‐continuity, weakly ‐continuity, almost θs‐continuity, and almost ‐continuity defined via closure operators. These concepts bridge the gap between classical and weak continuity and provide new insights into their relationships. We establish necessary and sufficient conditions under which these forms align with existing notions such as semi‐θs‐continuity, ‐continuity, weak continuity, and usual continuity, especially under specific constraints on the domain or codomain space. Our findings highlight both the common ground and

Abstract:

Abstract Feynman’s iϵ prescription for quantum field theoretic propagators has a quite natural reinterpretation in terms of a slight complex deformation of the Minkowski space-time metric. Though originally a strictly flat-space result, once reinterpreted in this way, these ideas can be naturally extended first to semi-classical curved-spacetime QFT on a fixed background geometry and then, (with more work), to fluctuating spacetime geometries. There are intimate connections with variants of the weak energy condition. We shall take the Lorentzian signature metric as primary, but note that allow
