Eighty Fifth Anniversary of Birthday and Scientific Legacy of Professor

The paper is concentrated on Professor Miloš Ráb and his contribution to the theory of oscillatory properties of solutions of second and third order linear differential equations, the theory of differential equations with complex coefficients and dynamical systems, and the theory of nonlinear second order differential equations. At the beginning, we take a brief look at the most important moments in his life. Afterwards, we describe his scientific activities on mentioned theories. Miloš Ráb – an outstanding mathematician Professor Miloš Ráb was well remembered by the 20th century mathematicians in the Czech lands and worldwide. A number of papers, such as [44], were written on 2010 Mathematics Subject Classification: primary 01A70; secondary 34C10, 34D05.
