Title: A Goldstone Theorem in Thermal Relativistic Quantum Field Theory

Abstract: We prove a Goldstone Theorem in thermal relativistic quantum
field theory, which relates spontaneous symmetry breaking to the rate
of space-like decay of the two-point function. The critical rate of
fall-off coincides with that of the massless free scalar field theory.
Related results and open problems are briefly discussed.
