Constrained KP hierarchies: additional symmetries, Darboux–Bäcklund solutions and relations to multi-matrix models

H Aratyn, E Nissimov, S Pacheva - International Journal of Modern …, 1997 - World Scientific
This paper provides a systematic description of the interplay between a specific class of
reductions denoted as cKP r, m (r, m≥ 1) of the primary continuum integrable system—the …

A Lax representation for the vertex operator and the central extension

M Adler, T Shiota, P Van Moerbeke - Communications in mathematical …, 1995 - Springer
Integrable hierarchies, viewed as isospectral deformations of an operator L may admit
symmetries; they are time-dependent vector fields, transversal to and commuting with the …

Supersymmetric two-boson equation, its reductions and the nonstandard supersymmetric KP hierarchy

JC Brunelli, A Das - International Journal of Modern Physics A, 1995 - World Scientific
In this paper, we review various properties of the supersymmetric Two-Boson (sTB) system.
We discuss the equation and its nonstandard Lax representation. We construct the local …

Topological Landau-Ginzburg theory with a rational potential and the dispersionless KP hierarchy

S Aoyama, Y Kodama - Communications in mathematical physics, 1996 - Springer
Based on the dispersionless KP (dKP) theory, we study a topological Landau-Ginzburg (LG)
theory characterized by a rational potential. Writing the dKP hierarchy in a general form …

Method of squared eigenfunction potentials in integrable hierarchies of KP type

H Aratyn, E Nissimov, S Pacheva - Communications in mathematical …, 1998 - Springer
The method of squared eigenfunction potentials (SEP) is developed systematically to
describe and gain new information about the Kadomtsev–Petviashvili (KP) hierarchy and its …

The supersymmetric two boson hierarchies

JC Brunelli, A Das - Physics Letters B, 1994 - Elsevier
We construct the most general supersymmetric two boson system that is integrable. We
obtain the Lax operator and the nonstandard Lax representation for this system. We show …

Toda lattice hierarchy and generalized string equations

K Takasaki - Communications in mathematical physics, 1996 - Springer
String equations of the p th generalized Kontsevich model and the compactified c= 1 string

Integrable discretizations for classical Boussinesq system

W Huang, L Xue, QP Liu - Journal of Physics A: Mathematical …, 2021 - iopscience.iop.org
In this paper, we propose and study integrable discrete systems related to the classical
Boussinesq system. Based on elementary and binary Darboux transformations and …

Darboux transformations for the supersymmetric two-boson hierarchy

XX Niu, QP Liu, L Xue - Acta Applicandae Mathematicae, 2022 - Springer
In this paper we construct Darboux transformations and Bäcklund transformations for the
supersymmetric two-boson hierarchy. Three Darboux transformations and associated …
