A Pluzhnikov's Theorem, Brownian motions and Martingales in Lie Group with skew-symmetric connections

S. N. Stelmastchuk

Let $G$ be a Lie Group with a left invariant connection such that its connection function is skew-symmetric. Our main goal is to show a version of Pluzhnikov's Theorem for this kin…

An equivalence between harmonic sections and sections that are harmonic maps

S. N. Stelmastchuk

Let $π : (E, \nabla^{E}) \to (M, g)$ be an affine submersion with horizontal distribution, where $\nabla^{E}$ is a symmetric connection and $M$ is a Riemannian manifold. Let $σ$ be a s…

A characterization of Einstein manifolds

S. N. Stelmastchuk

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 know…

Stochastic characterization of harmonic sections and a Liouville theorem

S. N. Stelmastchuk

Let $P (M, G)$ be a principal fiber bundle and $E (M, N, G, P)$ be an associate fiber bundle. Our interested is to study harmonic sections of the projection $π_{E}$ of $E$ into $M$ . Our…
