Brief abstract: A dusty plasma with strong interparticle interaction is considered. Such a system consists of plasma particles, as well as micro- and nanoscale particles with a condensed dispersed phase. Dusty plasma is found in many natural, laboratory phenomena and inmodern technology. It forms such a structure as a plasma crystal, called the "fifth state of matter." Fundamental issues and technological applications of dusty plasma physics as an open system are considered.Tel: 2727825, 87055357607.Email: firstname.lastname@example.org.Deputy Chairman of Seminar: Somsikov V.M.
