Quark-Gluon Plasma and Lattice

At high temperatures (and densities), strongly interacting matter is believed to exist in a deconfined state, called quark-gluon plasma. Nonperturbative studies of QCD using lattice regularization are essential for understanding the properties of this state. In this talk, I will discuss some relevant lattice results and how they help us in understanding properties of the quark-gluon plasma.
