摘要：
The order e5 contribution to the pressure of massless quantum electrodynamics at nonzero temperature is determined explicitly. An identity is also obtained relating a gauge-invariant piece of the pressure at order e2n+3 (n greater-than-or-equal-to 1) (from diagrams with only one fermion loop) to the pressure at order e2n. Prospects for higher order calculations are discussed and potential applications are mentioned.
