Generalized Einstein manifolds [PDF]
, 1989 summary:[For the entire collection see Zbl 0699.00032.] \par A manifold (M,g) is said to be generalized Einstein manifold if the following condition is satisfied $$ (\nabla\sb XS)(Y,Z)=\sigma (X)g(Y,Z)+\nu (Y)g(X,Z)+\nu (Z)g(X,Y) $$ where S(X,Y) is the ...

The Heythrop Journal, EarlyView.Abstract In this essay I contend that, whatever one might say about F.W.J. Schelling's historical and conceptual influence on Paul Tillich's doctrines, the overall style of Tillich's project can helpfully be dubbed Schellingian to the extent it mixes together discourses, genres, and vocabularies into an ever‐expanding whole. To the extent that anything

LP-Kenmotsu Manifolds Admitting Bach Almost Solitons
Universal Journal of Mathematics and ApplicationsFor a Lorentzian para-Kenmotsu manifold of dimension $m$ (briefly, ${(LPK)_{m}}$) admitting Bach almost soliton $(g,\zeta,\lambda)$, we explored the characteristics of the norm of Ricci operator. Besides, we gave the necessary condition for ${(LPK)_{m}}

A spinorial energy functional: Critical points and gradient flow
, 2012 On the universal bundle of unit spinors we study a natural energy functional whose critical points, if dimM C 3, are precisely the pairs (g,φ) consisting of a Ricci-flat Riemannian metric g together with a parallel g-spinor φ.

Lonergan, Decolonization and First Nations Peoples: An Apologetic from an Insider on the Outside
Modern Theology, EarlyView.Abstract The purpose of this article is to respond critically to a research project initiated out of the Board of the Lonergan Research Institute that seeks to expose colonialist assumptions in Lonergan's thought. Some of the initiatives seek to link Lonergan with complicity in Canadian residential schools, spiritual violence, and cultural genocide ...

Middlebrow Aesthetics: An Explanation and Defense
Pacific Philosophical Quarterly, EarlyView.ABSTRACT We offer a philosophical account of the middlebrow as a theoretical category to do explanatory and critical work in aesthetics. On our account, the middlebrow ought to be understood as aspirational popular art. That is, it is art which aspires both to be popular (in a distinctive sense), and at the same time to be something more than popular ...

Novi Sad Journal of Mathematics, 2015 Summary: The object of this paper is to define and study a new type of non-flat Riemannian manifolds called nearly Einstein manifolds. The notion of this nearly Einstein manifold has been established by an example and an existence theorem. Some geometric properties are obtained.

Philosophy and Phenomenological Research, EarlyView.ABSTRACT Determinism is (roughly) the thesis that the past determines the future. But efforts to define it precisely have exposed deep methodological disagreements. Standard possible‐worlds formulations of determinism presuppose an “agreement” relation between worlds, but this relation can be understood in multiple ways, none of which is particularly ...

On Indefinite Almost Paracontact Metric Manifold
, 2014 The object of the present paper is to introduce special ( ∈)− para Sasakian manifold and to study some of its properties. We have shown that a recurrent special ( ∈)−para Sasakian manifold with η as 1-form of recurrence is Einstein manifold. Among others,
