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 Irreducible representations of compact groups
For representations over complex numbers and compact groups - all irreps are finite-dimensional - see nice answers on mathoverflow.net/questions/119402/…

Yes character table seems to give same info as representation RING - which is not enough.

Thank you very much for your very interesting answer ! If it would be possible to add more comments, why topic is important in algebraic geometry that would be very kind of you. As a small remark on "...and the language of category, which was becoming popular at that time...", it seems neither Tanaka (1938), nor Krein (1949) used the language of categories. Krein seems used something "block-algebras" also called "Krein-algebras". I wonder when the language of categories stared to be used for this topic ?
