摘要：
A complex contour integral method is constructed and applied to the Becchi-Rouet-Stora-Tyutin (BRST) quantization procedure of string theories on higher genus Riemann surfaces with N = 0 and 1 Krichever-Novikov (KN) algebras. This method makes calculations very simple. It is shown that the critical spacetime dimension of the string theories on a genus-g Riemann surface equals that of the string theories on a genus-zero Riemann surface, and that the "Regge intercepts" in the genus-g case are alpha(g) = 1 - 3/4g - 9/8g2 and 1/2 - 3/4g - 17/16g2 for bosonic strings and superstrings, respectively.
