Emptiness Formation Probability of the Six-Vertex Model and the Sixth Painlevé Equation

We show that the emptiness formation probability of the six-vertex model with domain wall boundary conditions at its free-fermion point is a τ -function of the sixth Painlevé equation. Using this fact we derive asymptotics of the emptiness formation probability in the thermodynamic limit.
