This issue is devoted to the memory of Professor Yu.L.Klimontovich, an outstanding theorist whose ideas and works have been a great contribution to modern kinetic theory and statistical mechanics. Without his fundamental papers and books it is impossible to imagine many fields of theoretical physics (such as statistical plasma theory, kinetic description of nonequilibrium processes in non-ideal gas and non-ideal plasmas, theory of turbulence, theory of open systems, fluctuations in quantum and relativistic systems, etc.).
