High-temperature field theory in curved spacetime. (English) Zbl 0990.81573

Summary: We establish, to all orders in Newton’s constant, the form of the effective actions describing hard-thermal matter loops in curved spacetime, both with external gluon lines \((T^{2}\) effects) and without \((T^{4}\) effects). In the latter case, the energy-momentum tensor corresponding to the effective action action has T\(^{00}>0\).
