Sasakian Geometry, Holonomy, and Supersymmetry

, 2007
In this expository article we discuss the relations between Sasakian geometry, reduced holonomy and supersymmetry. It is well known that the Riemannian manifolds other than the round spheres that admit real Killing spinors are precisely Sasaki-Einstein ...

Iterated Relation Systems on Riemannian Manifolds

Fractal and Fractional
For fractals on Riemannian manifolds, the theory of iterated function systems often does not apply well directly, as these fractal sets are often defined by relations that are multivalued or non-contractive.

A remark on infinity-harmonic functions on Riemannian manifolds

Electronic Journal of Differential Equations, 1995
functions on Riemannian manifolds. As a corollary, there is no non-constant $infty$-harmonic function on positively (or negatively) curved manifolds.

Slant submersions from almost paracontact Riemannian manifolds

Kuwait Journal of Science, 2015
In this paper, we introduce slant submersions from almost paracontact Riemannian manifoldsonto Riemannian manifolds. We give examples and investigate the geometry of foliationswhich are arisen from the definition of a Riemannian submersion.

p-convex Riemannian manifolds

Inventiones Mathematicae, 1986
Let M be an n-dimensional compact connected Riemannian manifold with non- empty boundary. We say that the boundary is p-convex (where p is an integer with \(1\leq p\leq n-1)\) if at each point the sum of any p principal curvatures, defined with respect to the inward normal, is positive.

Transversal Lightlike Submersions

Journal of Advanced Research in Natural and Applied Sciences
In this paper, we introduce the concept of transversal lightlike submersions from semi-Riemannian manifolds onto semi-Riemannian manifolds. Specifically, we present the concepts of transversal r-lightlike and isotropic transversal lightlike submersions ...

Stability of vertical minimal surfaces in three-dimensional sub-Riemannian manifolds

Pracì Mìžnarodnogo Geometričnogo Centru
We obtain first and second variation formulae for minimal surfaces in three-dimensional sub-Riemannian manifolds which are vertical, i.e., perpendicular to the horizontal distribution of the sub-Riemannian structure.
