. * His research interests include functional analysis, mathematical physics and stochastic calculus. * Y. Kondratiev is a member of the Kyiv school of functional analysis founded by M. Krein and lead, for many years, by Y. Berezansky. * His interests in mathematical physics were inspired by cooperation with the Moscow seminar in statistical Physics ( R. Dobrushin, R. Minlos, Y. Sinai). Yuri's collaboration with A. Skorokhod has influenced most of his subsequent papers on stochastics.
