Emil Horozov (born 27 September 1949, Sofia) is a Bulgarian mathematician known for his work in dynamical systems theory and mathematical physics and work related to Hilbert's sixteenth problem.
Horozov obtained his Ph.D. from Moscow State University in 1978 under the supervision of V. I. Arnold and Y. V. Egorov.
Among his best known mathematical works are "Versal deformations of equivariant vector fields for cases of symmetry of order two and three" (Ph.D. thesis, 1979), "On the number of limit cycles in perturbations of quadratic Hamiltonian systems" (joint with I. D. Iliev), "Some functions that generalize the Krall-Laguerre polynomials" (joint with F. A Grünbaum and L. Haine), and "Perturbations of the spherical pendulum and Abelian integrals".
He was the head of the Bulgarian National Science Fund until his resignation in February 2011 after suffering reprisals for combating corruption in the institution. In 2014 Sofia University decided to retire prematurely Professor Emil Horozov contrary to the rules and the practice of the University. 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.
