Emil Horozov

Emil Horozov (27 September 1949 – 13 January 2026, in Sofia ) was a Bulgarian mathematician known for his work in dynamical systems theory and mathematical physics and work related to Hilbert's sixteenth problem.

Education Horozov obtained Master's degree from Sofia University in 1972 and then got his Ph.D. from Moscow State University in 1978, where he was under the supervision of V. I. Arnold and Y. V. Egorov. His thesis was Bifurcations of symmetric vectorfields on the plane. In 1990, Horozov obtained his D.Sc. degree, this time from Sofia University, after completing his thesis, which was titled Hamiltonian systems and Abelian integrals. In 2014 Sofia University decided to retire prematurely Professor Emil Horozov contrary to the rules and the practice of the University. In this relation an open Letter addressed to the Rector Ivan Ilchev and the Members of the Academic Council of Sofia University “St. Kliment Ohridski’’ was published in the Newsletter of the European Mathematical Society. The letter has not received an official answer. Later the first instance Bulgarian court has decided that the act of Sofia University violates the law and that Professor Horozov must be returned to his job.
