# Department of Integral and Differential Equations

Visit Site of Department of Integral and Differential Equations

The department provides teaching of the courses of differential equations, integral equations and the elements of functional analysis, calculus of variations and optimization methods, dynamical systems, Foundations of actuarial and financial analysis.

The department staff study topical problems of the theory of integral and invariant sets of nonlinear dynamical systems, asymptotic methods and methods of averaging of nonlinear mechanics, the theory of impulsive systems, numerical-analytical methods for solving boundary value problems, multi-frequency oscillations in Hamiltonian systems, asymptotic behavior of solutions of differential equations, the theory of nonlinear evolution equations and inclusions, the stability theory of stochastic differential equations, the qualitative behavior of solutions of multivalued evolution systems, the theory of optimal control.
