              Nuclear Equation of State

Nuclear equation of state plays an essential role in the
evolution of the Universe, in supernovae explosions, and thus
in heavy-element production, and in stability of neutron
stars.  The equation constrains the two- and three-nucleon
interactions and the quantum chromodynamics in the
nonperturbative regime. Despite the importance of the equation,
its features remained, though, fairly obscure.  The talk
reviews new results on the equation of state emerging from 
measurements of giant nuclear oscillations and from studies of
particle emission in central collisions of heavy nuclei.
