Korolyuk in the development of the theory of probability and mathematical statistics in connection with his 75th birthday. This paper does not deal with the results of Korolyuk in the problems of cybernetics and in the applied aspects of his activity. The paper contains five sections: Asymptotical analysis in the boundary problems for random walks and Poisson processes; Potential method in the boundary problems for processes with independent increments and random walks; Boundary problems for semi-Markov walks on the superposition of two renewal processes; Asymptotical problems for semi-Markov processes and foundations of phase merging; Theory of random evolutions and their applications.
