关于矩阵修正的KP族

On matrix modified KP hierarchy

A. Zabrodin

摘要:

使用双线性形式主义,我们认为多组分和矩阵修改的KP层次。主要的工具是双线性恒等式的τ-函数,这是实现作为一个期望值的Clifford群元素组成的多组分费米子运营商。我们还构造了Baker-Akhiezer函数,并推导出它们所满足的辅助线性方程。

英文摘要:

Using the bilinear formalism, we consider multicomponent and matrix modified KP hierarchies. The main tool is the bilinear identity for the tau-function which is realized as an expectation value of a Clifford group element composed from multicomponent fermionic operators. We also construct the Baker-Akhiezer functions and derive auxiliary linear equations satisfied by them.
