Main research aims Equation of state for
nuclear matter in wide T and
density region Subnuclear degrees of freedom
(q,g) their collective behaviour
(QGP,QAP,) Hadron properties in hot dense
matter mass, width, cross
sections Exotic particle production
pentaquark, strangelets, Astrophysical
aspects nuclear reactions in
matter at finite T
