We show asymptotic completeness for the charged Klein–Gordon equation in exterior De Sitter–Reissner–Nordström spacetime when product of charge black with Klein-Gordon field is small enough. then interpret scattering as transports along principal null geodesics a Kaluza–Klein extension original spacetime.

In most professions, images of exemplary practitioners influence practice powerfully, and adult education is no exception in this regard. In the adult education literature, arguably the most influential images of exemplary adult educators include the following: (a) Belenky, Clinchy, Goldberger, & Tarule's midwife (1986), (b) Brookfield's skillful teacher (1 990), (c) Daloz's mentor (1 986), (d)...

Inflaton field governed universe from NKK theory of gravity: stochastic approach. Abstract We study a nonperturbative single field (inflaton) governed cosmological model from a 5D Noncompact Kaluza-Klein (NKK) theory of gravity. The inflaton field fluctuations are estimated for different epochs of the evolution of the universe. We conclude that the inflaton field has been sliding down its (quad...

A formalization of the recently introduced formalism for inflation is developed from a noncompact Kaluza-Klein theory. In particular, the case for a single scalar field inflationary model is studied. We obtain that the scalar potential, which assume different representations in different frames, has a geometrical origin. In the last years, many people has worked in extra dimensions [1]. As has ...

As a specific kind of non-Euclidean metric lies in projective space, Cayley-Klein metric has been recently introduced in metric learning to deal with the complex data distributions in computer vision tasks. In this paper, we extend the original Cayley-Klein metric to the multiple Cayley-Klein metric, which is defined as a linear combination of several Cayley-Klein metrics. Since Cayley-Klein is...

Abstract A negative shortwave cloud feedback associated with higher extratropical liquid water content in mixed-phase clouds is a common feature of global warming simulations, and multiple mechanisms have been hypothesized. set process-level experiments performed an idealized climate model (a dynamical core passive tracers full Rotstayn–Klein single-moment microphysics) show that the picture pa...
