The matrix-resolvent method to tau-functions for the nonlinear Schrödinger hierarchy
Ang Fu, Di Yang
We extend the matrix-resolvent method of computing logarithmic derivatives of tau-functions to the nonlinear Schrödinger (NLS) hierarchy. Based on this method we give a detailed p…
Wave functions and k-point functions for the AKNS hierarchy
Ang Fu
For an arbitrary solution to the AKNS hierarchy, the logarithmic derivatives of the tau-function of the solution can be computed by the matrix-resolvent method [14,21]. In this pap…
Consistency of a kind of general noncanonical warm inflation
Xiao-Min Zhang, Ang Fu, Kai Li +4
The framework of a kind of noncanonical warm inflation is introduced, and the dynamical equations of this scenario are presented. We propose the slow roll approximations and give s…
The constrained KP hierarchy and the bigraded Toda hierarchy of -type
Ang Fu, Di Yang, Dafeng Zuo
In this paper, we extend the matrix-resolvent method to the study of the Dubrovin--Zhang type tau-functions for the constrained KP hierarchy and the bigraded Toda hierarchy of $(M,…
