On curves and curvatures
To express the curvatures of curves in euclidean plane and space is a very standard differential geometric exercise. In the formulas, with respect to a general parametrization of the curve, volumes of parallelograms determined by fi...

QUALITATIVE AND NUMERICAL ASPECTS OF A MOTION OF A FAMILY OF INTERACTING CURVES IN SPACE
In this article we investigate a system of geometric evolution equations describing a curvature driven motion of a family of three-dimensional curves in the normal and binormal directions. Evolving curves may be the subject...

Invariant measures and boundedness in the mean for stochastic equations driven by Levy noise
Existence of invariant measures and average stability in the mean are studied for stochastic differential equations driven by Levy process. In particular, some natural conditions are found that verify stabilization of the equati...
