Archaeometry, EarlyView.Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

Einstein manifolds with skew torsion [PDF]
arXiv, 2012 This paper is devoted to the first systematic investigation of manifolds that are Einstein for a connection with skew symmetric torsion. We derive the Einstein equation from a variational principle and prove that, for parallel torsion, any Einstein manifold with skew torsion has constant scalar curvature; and if it is complete of positive scalar ...

The Individuality of Meaning in Life
European Journal of Philosophy, EarlyView.Abstract In contemporary philosophical discourse, there is a widespread assumption that meaning in life is individual: that it is a value inherent in individual human lives, that the content of this meaning varies from individual to individual, and that it differs in degree based on the individual. Despite these claims, however, objectivist theories of

A characterization of Einstein manifolds
, 2009 In this work we wish characterize the Einstein manifolds $(M,g)$, however without the necessity of hypothesis of compactness over $M$ and unitary volume of $g$, which are well known in many works. Our result says that if all eingenvalues $ $ of $r_{g}$, with respect to $g$, satisfy $ \geq \frac{1}{n}s_{g}$, then $(M,g)$ is an Einstein manifold, where

A Kähler Einstein structure on the tangent bundle of a space form
International Journal of Mathematics and Mathematical Sciences, 2001 We obtain a Kähler Einstein structure on the tangent bundle of a Riemannian manifold of constant negative curvature. Moreover, the holomorphic sectional curvature of this Kähler Einstein structure is constant.
