  • The book consists of abstracts of plenary lectures, oral reports andposters presented at the XXXIII International Conference on Equa-tions of State for Matter (16 March 2018, Elbrus and Tegenekli,Kabardino-Balkaria, Russia). The conference is devoted to the 40thanniversary of the I All-Union Session on Equations of State (Octo-ber 1978). The presentations deal with the contemporary investiga-tions in the field of physics of extreme states of matter. The confer-ence topics are as follows: equations of state and constitutive equa-tions for matter at high pressures and temperatures; shock waves,detonation and combustion physics; interaction of intense laser, x-ray and microwave radiation, powerful ion and electron beams withmatter; techniques of intense energy fluxes generation; experimen-tal methods of diagnostics of ultrafast processes; low-temperatureplasma physics; physical issues of power engineering and technologyaspects.

    The conference is supported by the Russian Academy of Sciencesand the Russian Foundation for Basic Research (grant No. 18-02-20015).

    Edited by Fortov V.E., Karamurzov B.S., Efremov V.P., Khish-chenko K.V., Sultanov V.G., Kadatskiy M.A., Andreev N.E., Dy-achkov L.G., Iosilevskiy I.L., Kanel G.I., Levashov P.R., Mint-sev V.B., Savintsev A.P., Shakhray D.V., Shpatakovskaya G.V.,Son E.E.

    The editorial board with deep regret announces the death of friendsand colleagues: Academician Evgeny Nikolaevich Avrorin (11 July1932 9 January 2018), who was the organizing committee memberof the Conferences on Equations of State for Matter and Interactionof Intense Energy Fluxes with Matter; Professor Valentin FedorovichKuropatenko (18 December 1933 13 October 2017), who was anactive participant in these meetings starting with the first session;Professor Mikhail Fedorovich Ivanov (29 September 1945 16 Oc-tober 2017), who was a regular participant of these conferences too.
