## The next general scientific seminar of the Mechanics and Mathematics faculty

11/02/2020The report presents nonlinear eigenvalue problems for completely regular linear Sturmian systems of fourth-order. Information will be provided on the oscillatory properties of eigenfunctions of fourth-order completely regular Sturmian systems and their derivatives with potential, on the structure of bifurcation points of non-linear systems for completely regular Sturmian systems, on the behavior in the space *R*x*C*^{3} of components of the solutions set of these nonlinear systems contained in classes of functions which have oscillatory properties of eigen-functions (and their derivatives) of linear systems.

We invite all of you to attend our seminar.
