我们研究了与(n,1)曲线相关的KP-族的τ函数。如果对应的tau函数为1。另一方面,如果τ函数成为时间变量的二次函数的指数。通过对后者应用顶点算子,我们得到了非零常数背景下的孤子解。
We study the tau function of the KP-hierarchy associated with an (n, 1) curve. Ifthe corresponding tau function is 1. On the other hand ifthe tau function becomes the exponential of a quadratic function of the time variables. By applying vertex operators to the latter we obtain soliton solutions on nonzero constant backgrounds.
