Sub-Geometries of Lie Sphere Differential Geometry.
We study the problem to extend an immersed circle f in the sphere S2 to an immersion of the disc. We analyze existence and uniqueness for this problems in terms of the combinatorial structure of a wor...

We study a system of N non-intersecting Brownian motions on a line seg-ment [0;L] with periodic, absorbing and re ecting boundary conditions.

In this paper we find examples of slant surfaces in the nearly K¨ahler six sphere. First, we characterize two-dimensional small and great spheres which are slant.
1.1. Background. A bi-Lipschitz homeomorphism f : X → Y between metric spaces is a mapping f such that f and f−1 satisfy a uniform Lipschitz condition.
