Mykhailo Kozlovskii's 70th birthday

Our colleague, professor Mykhailo Kozlovskii, the well-known Ukrainian scientist in the field of phase transitions and critical phenomena, turns 70 on August 30, 2022. The approach for treating critical behaviour of three-dimensional systems, initiated by academician Ihor Yukhnovskii and further developed by M. Kozlovskii, forms a new direction in phase transition theory.
