Aa. Bytsenko et Sd. Odintsov, THE MULTILOOP PARTITION-FUNCTION FOR A NONCRITICAL BOSONIC STRING AT NONZERO TEMPERATURE, Nuovo cimento della Societa italiana di fisica. B, Relativity, classical and statistical physics, 109(1), 1994, pp. 99-102
The Mellin-Barnes representation for the partition of a non-critical b
osonic string at non-zero temperature is constructed. The partition fu
nction is calculated at any genus. The critical (Hagedorn) temperature
is also found.
