Ihor Ostapovych Parasyuk

Doctor of physics and mathematics (1995), professor (2001).
2003-2007 - Dean of the Faculty of Mathematics and Mechanics.
He is the author of more than 70 scientific papers and the co-author of the textbook "Differential Equations" for universities students.
His main scientific achievements are concerned with the theory of quasiperiodic motions of Hamiltonian systems on coisotropic invariant tori, nonlocal existence theorems for quasiperiodic solutions of essentially nonlinear Lagrangian systems and for solutions of nonlinear singular boundary value problems on the half-line for ordinary differential equations.
