Rifkat Bogdanov

Rifkat Ibragimovich Bogdanov (Russian: Рифка́т Ибраги́мович Богда́нов; June 13, 1950 November 3, 2013) was a Soviet and Russian mathematician known for contributions to nonlinear dynamical systems, bifurcation theory, and differential geometry. He was an ethnic Tatar. In his work on bifurcations of limit cycles and versal deformations of singular points of vector fields (197576), he described a bifurcation of co-dimension 2, which has become known in the literature as the Bogdanov–Takens bifurcation.

Born in the village of Mamykovo in Tatarstan, Bogdanov had a doctorate in physico-mathematical sciences and was a professor in two Russian research organizations: the Skobeltsyn Institute of Nuclear Physics at Lomonosov Moscow State University and the Department of Higher Mathematics at MATI the Tsiolkovskii State Technological University.
