σ函数作为A Tau函数
Sigma Function as A Tau Function
摘要：
研究了嵌入泛Grassmann流形中的某条平面代数曲线（n，s）-曲线的仿射环所对应的τ函数。它可以用多变量σ函数简洁地表示。这个表达式反过来又被用来证明的σ函数在以前的文件中建立在一个不同的方法的级数展开的基本性质。
英文摘要：
The tau function corresponding to the affine ring of a certain plane algebraic curve, called (n,s)-curve, embedded in the universal Grassmann manifold is studied. It is neatly expressed by the multivariate sigma function. This expression is in turn used to prove fundamental properties on the series expansion of the sigma function established in a previous paper in a different method.
