* His research interests included functional analysis, mathematical physics and stochastic calculus. * Kondratiev was a member of the Kyiv school of functional analysis founded by M. Krein and led, 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. Provided by Wikipedia
