Theory of condensed matter (in memory of Yurii Vasil'evich Kopaev) (Scientific session of the Physical Sciences Division of the Russian Academy of Sciences, 13 December 2017)

A scientific session of the Physical Sciences Division of the Russian Academy of Sciences (RAS), dedicated to the memory of Academician Yurii Vasil'evich Kopaev and entitled “Theory of condensed matter”, was held at the Conference Hall of the Lebedev Physical Institute, RAS on 13 December 2017.
