Education
Moscow State University.
Moscow State University.
His research concerned Hamiltonian mechanics, perturbation theory, celestial mechanics, integrable systems, dynamical systems, the quasiclassical approximation, and singularity theory. He proved, in particular, a stability result in KAM-theory stating that, under certain conditions, solutions of nearly integrable systems stay close to invariant tori for exponentially long times (Giorgilli 1989). Nekhoroshev was professor of the Moscow State University and University of Milan.
He is an alumnus of Moscow"s boarding school northern
