Novikov Steklov Mathematical Institute, Moscow, Russia e-mail: snovikov@mi.ras.ru A new approach to the discretization of complex analysis has been developed in a series of papers by the author and I. A. Dynnikov during several years. ... We have also developed a new method for the discretization of differential geometric connections on simplicial polyhedra. ...

Top ological toric theory Mikiya Masuda Osaka City University, Japan e-mail: masuda@sci.osaka-cu.ac.jp The theory of toric varieties was established in 1970's. It can be thought of as a bridge connecting algebraic geometry and combinatorics. But one can develop the theory purely in terms of topology to some extent, and it turns out that there is an analogous (expanded, in some sense) bridge between topology and combinatorics. I will discuss the connection between topology and combinatorics.
Krasovskii's Extreme Shift Control Principle and Its Applications Yuri S. Osipov Russian Academy of Sciences, Moscow, Russia Arkady V. Kryazhimskiy IIASA, Austria / Steklov Mathematical Institute, Russia e-mail: kryazhim@iiasa.ac.at In the beginning of the 1970s, N. N. Krasovskii proposed a new method of closed-loop control of dynamical systems affected by uncertain nonobservable disturbances -- the extreme shift control principle. ...

... A particularly interesting family of examples are given by the weighted projective spaces CP n (), which depend upon a vector of positive integral weights (0 ,...,n ) for their definition. ... Nevertheless, the ultimate goal is to outline recent work with Tony Bahri and Matthias Franz, in which we compute the equivariant integral cohomology ring HT (CP n ()), with respect to the action of the standard compact n-torus T < (C \ 0)n . ...

Our theory is twofold: 1. ... With the Maximum Principle, assuming the minimization of a criterion which is a compromise b etween the absolute work and some other term (comfort term), we prove that inactivations must appear. ...
On synthesizing impulsive controls and the theory of fast controls Aleksandr B. Kurzhanski Moscow State University, Moscow, Russia e-mail: kurzhans@mail.ru, kurzhan@cs.msu.su The report deals with the problem of constructing closed-loop (feedback) controls for systems that allow impulsive control inputs described through generalized "delta" functions and their derivatives. Such problems, having had a serious applied motivation, were mostly considered within the framework of open-loop control. ...
Statistics in Morse theory of smo oth functions Vladimir I. Arnold Steklov Mathematical Institute, Moscow, Russia e-mail: arnold@mi.ras.ru There are exactly 17746 topologically distinct Morse functions with 4 saddles on the two dimensional sphere. This result basing on combinatorics of random graphs was obtained only two years ago within an investigation of Hilbert's 16th problem on topological classification of polynomials in real algebraic geometry. ...
Control theory and nonsmo oth analysis Francis Clarke Institut Universitaire de France and Universitґ de Lyon, France e e-mail: clarke@math.univ-lyon1.fr One of the lessons of the last decades is that as soon as nonlinear replaces linear, it becomes highly likely that nonsmoothness will arise as an issue. This has been notably the case in partial differential equations, in optimal control, and in stabilizing feedback design. ... We shall examine in particular the role played by nonsmooth analysis. ...
