双圈超弦振幅与S_6表示

Two loop superstring amplitudes and S_6 representations

Sergio Cacciatori, Francesco Dalla Piazza

摘要:

本文描述了如何利用群的表示理论来简化弦论中两个圈配分函数的推导过程,给出了D'Hoker和Phong [1]结果中出现的模形式的一个内在描述.该方法的优点是只利用了模函数的代数性质,并可推广到任意亏格g。

英文摘要:

In this paper we describe how representation theory of groups can be used to shorten the derivation of two loop partition functions in string theory, giving an intrinsic description of modular forms appearing in the results of D'Hoker and Phong [1]. Our method has the advantage of using only algebraic properties of modular functions and it can be extended to any genus g.
