Einstein solvmanifolds: existence and non-existence questions
, 2010 The general aim of this paper is to study which are the solvable Lie groups admitting an Einstein left invariant metric. The space N of all nilpotent Lie brackets on R^n parametrizes a set of (n+1)-dimensional rank-one solvmanifolds, containing the set ...

Existence of log canonical closures [PDF]
, 2012 Let $f:X\to U$ be a projective morphism of normal varieties and $(X,\Delta)$ a dlt pair. We prove that if there is an open set $U^0\subset U$, such that $(X,\Delta)\times_U U^0$ has a good minimal model over $U^0$ and the images of all the non-klt ...

Existence and non-existence of minimal graphs
Journal de Mathématiques Pures et Appliquées, 2023 We study the Dirichlet problem for minimal surface systems in arbitrary dimension and codimension via mean curvature flow, and obtain the existence of minimal graphs over arbitrary mean convex bounded $C^2$ domains for a large class of prescribed boundary data.

Gunky time and indeterminate existence [PDF]
, 2017 The paper criticizes an argument recently presented by Ross Cameron. The argument purports to show that, if time is gunky (that is, if there are no time atoms), and if changes in existence are underwritten by events of coming to be, then there are cases ...

Existence of symmetric central configurations [PDF]
, 2014 Central configurations have been of great interest over many years, with the earliest examples due to Euler and Lagrange. There are numerous results in the literature demonstrating the existence of central configurations with specific symmetry properties,

Heidegger's Account of Platonic Idealism as Origin of Aesthetics [PDF]
حکمت و فلسفه, 2012 While the ancient Greek never had a specific term for what we know today as art, they used poiesis and techne to refer to concepts broader than contemporary fine arts. Poiesis meant "to make" and "to bring forth".
