在Krichever-Novikov(简称KN)弦的BRST量子化的基础上,采用Siegel的方法构造了任意给定亏格的KN弦的拟自由场论,并提出了一种非微扰拟自由弦场论的尝试。Based on the BRST quantization, a quasi-free field theory for the Krichever-Novikov string on arbitrary genus Riemann surface has been given in analog to the Siegel approach to free closed string field theory. A non-purtubative formalism has also been suggested.
