Started as A.A. Kirillov's student in rerpresentation theory in Moscow State University. Got PhD in 1999. Worked in ITEP Moscow for 10 years somewhere in between representation theory, integrable systems and algebraic geometry, in particular geometric Lanlgands and its connection to Hitchin-Gaudin integrable systems.
Currently in industry: quantitative finance, previously in wireless telecommunication doing applied math.: information theory, error-correcting codes, statistical estimation theory, numerical algorithms.
Deeply worried about the ITEP very unfortunate situation: http://saveitep.org

Leading Russian research center is in danger. More than 850 scientists signed letter to president and prime-minister asking for help. Fields medalists M. Atiyah, L. Lafforgue, E. Witten, Nobel Prize winner D. Gross, mathematicians A. Beilinson, I. Cherednik, B. Dubrovin, P. Etingof, B. Feigin, A. Kirillov, I. Krichever, N. Reshetikhin, E. Vinberg, physicists J. Cardy (Oxford), M. Douglas, J. Froehlich, J. Maldacen (IAS), N. Nekrasov(IHES, ITEP), B. de Wit, are among them.

I worked in ITEP more than 10 years, I learned a lot from these people and it is really one the best institutes in Russia and world. Like many colleagues I am really afraid that current situation is step by step programm of killing ITEP. Last year newly instead director made from research institute "GULAG-light" as said Prof. Stan Brodsky from Stanford said after seeing all this.

comment Can (how) one distinguish germs of continuous functions by a countable set of params?
Function on germs: IF germ has derivative, then F(germ)=derivative, ELSE zero. This function seems to me quite "nice" and "constructive". Seems we do not need AC to define it. In contrast to your another example - "reals/rational translation" - it seems to me for that example there is NO "nice" function at all, is it correct ? So may be these two examples are different ? Pay attention that germs correspond to tail of sequences which have limit - may be property of having limit change something...

Remark. It seems to me fractal dimension is "nice" function on germs. But it seems you say that there are NO "nice" functions on germs (AC is necessary).... Some contradiction in my head

Germs = function/equivalence relation. It seems to me we can choose representative by definition - choose an a element in subset of equivalent functions. What is wrong ? And yes, it gives answer to my question, of course, it is not the anwer I hoped to, but formally it is an answer. I'll think how to modify my question to avoid this answer, but let me do it later...

Why do we need to choose representative ?
