Bernoulli-Euler numbers and multiboundary singularities of type $B_{n}^{l}$

Oleg Karpenkov

In this paper we study properties of numbers $K_{n}^{l}$ of connected components of bifurcation diagrams for multiboundary singularities $B_{n}^{l}$ . These numbers generalize classic Berno…

Rational approximation of the maximal commutative subgroups of GL(n,R)

O. Karpenkov, A. Vershik

How to find "best rational approximations" of maximal commutative subgroups of GL(n,R)? In this paper we pose and make first steps in the study of this problem. It contains both cl…
