Characterizing ϕRic-Vector Fields and Quasi-Einstein Manifolds on Multiply Warped Product Manifolds
International Journal of Mathematics and Mathematical SciencesWe characterize multiply warped product manifolds with ϕRic-vector fields. We give the necessary and sufficient conditions for the lift of a vector field on a factor manifold to be the ϕRic-vector field.

Mathematics, 2019 In the present paper, we study conformal mappings between a connected n-dimension pseudo-Riemannian Einstein manifolds. Let g be a pseudo-Riemannian Einstein metric of indefinite signature on a connected n-dimensional manifold M.

British Journal of Developmental Psychology, EarlyView.Abstract Young children spend an increasing amount of time engaging with screens, including television viewing. Although most research has focused on the quantity of children's viewing, growing evidence suggests that the developmental effects of screen media depend on the quality and characteristics of the content.

Children &Society, EarlyView.ABSTRACT This article interrogates the politics of othering embedded in the taken‐for‐granted association of childhood, play, joy, and happiness. It explores how these notions are historically inscribed as forms of otherness tied to the affective normativity of joy.

Evolution paths on the equilibrium manifold [PDF]
In a pure exchange smooth economy with fixed total resources, we de- fine the length between two regular equilibria belonging to the equilibrium manifold as the number of intersection points of the evolution path connecting them with the set of critical ...

Toward an Ecumenical Metaphysics? A Response to Reviewers of Christ the Logos of Creation
International Journal of Systematic Theology, EarlyView.Abstract After a series of promising ecumenical meetings in 1929 and 1931 with the Jesuit Erich Przywara, who advocated an analogical understanding of the relationship between God and world – doing so in part to ward off the danger posed by modern forms of pantheism – Karl Barth abruptly threw down the gauntlet and presented a serious obstacle to ...

Geometric Characterizations of Riemann Solitons
Journal of MathematicsIn this paper, we find the geometric characterizations of Riemann solitons within the background of co-Kähler manifolds admitting semisymmetric metric ζ-connection. Let g,V be a Riemann soliton on a co-Kähler manifold M admitting a semisymmetric metric ζ-

Journal of Microscopy, EarlyView.Abstract AFM is not for the faint of heart. It has never been for these 40 years since its invention or for any of the modalities that have emerged. And among them, the initial concept of using AFM to measure cell mechanics was simply brazen. On the one hand, those pioneers hacked an imaging tool optimised for minimal mechanical interaction between ...

Vortices in trapped bose - Einstein condensates [PDF]
, 2000 In this thesis we solve the Gross-Pitaevskii equation numerically in order to model the response of trapped Bose-Einstein condensed gases to perturbations by electromagnetic fields.
