Misha Verbitsky (Russian: Ми́ша Верби́цкий, born June 20, 1969 in Moscow) is a Russian mathematician. He is currently working at the Instituto Nacional de Matemática Pura e Aplicada, Rio de Janeiro. However, he is primarily known to the general public as a controversial critic, political activist and independent music publisher. Scientific activities Verbitsky graduated from a Math class in the Moscow State School 57 in 1986, and was active in mathematics since then. His principal area of interest in mathematics is differential geometry, especially geometry of hyperkähler manifolds and locally conformally Kähler manifolds. He proved an analogue of the global Torelli theorem for hyperkähler manifolds and the mirror conjecture in hyperkähler case. He also contributed to the theory of Hodge structures. His PhD thesis called Cohomology of compact Hyperkaehler Manifolds was defended in 1995 at Harvard University under supervision of David Kazhdan. He held different positions, most prominently at the Independent University of Moscow (since 1996), Glasgow University...
