The Equivalence Problem for Five-dimensional Levi Degenerate CR Manifolds
, 2012Let M be a CR manifold of hypersurface type, which is Levi degenerate but also satisfying a k-nondegeneracy condition at all points. This might be only if dim M is greater than or equal to 5 and if dim M = 5, then k= 2 at all points.

Reduction of Five-Dimensional Uniformly Levi Degenerate CR Structures to Absolute Parallelisms
, 2012Let ${\mathfrak{C}}_{2,1}$ be the class of connected 5-dimensional CR-hypersurfaces that are 2-nondegenerate and uniformly Levi degenerate of rank 1. We show that the CR-structures in ${\mathfrak{C}}_{2,1}$ are reducible to ${\mathfrak{so}}(3,2)$-valued ...

Levy διαδικασίες G-Levy διαδικασίες
2012Sublinear expectation spaces consist the suitable framework in which problems of classical case involve a family of singular measures. In the current thesis Levy processes defined in Sublinear Expectation Sapaces are studied.

AbstractAn analogy of Levi sums is considered for a class of stochastic partial differential equations to construct their stochastic fundamental solutions. These notions are shown to coincide with Donsker's delta functions, typical generalized Wiener functionals, which have been studied in the frame of the Malliavin calculus.

Let G be a group. G is called an n-abelian group if \((xy)^ n=x^ ny^ n\) for the integer n and all x,y\(\in G\). G is called an n-Levi group if \((x^ n,y)=(x,y)^ n\) for the integer n and all x,y\(\in G\). G is called an n-Bell group if \((x^ n,y)=(x,y^ n)\) for the integer n and all x,y\(\in G.\) The exponent semigroup of G is defined as the set of ...
