Sasa–Satsuma type matrix integrable hierarchies are generated from taking two group
reductions of replacing the spectral parameter with its complex conjugate and its negative in …

Two simultaneous nonlocal group constraints of the Ablowitz-Kaup-Newell-Segur matrix
eigenvalue problems are discussed, of which one constraint changes the eigenvalue …

We aim to discuss about how to construct and classify nonlocal PT-symmetric integrable
equations via nonlocal group reductions of matrix spectral problems. The nonlocalities …

We present mixed-type reduced soliton hierarchies of nonlocal integrable nonlinear
Schrödinger equations of arbitrary even order by conducting two nonlocal group reductions …

We would like to propose a kind of nonlocal real reverse-spacetime integrable hierarchies of
PT-symmetric matrix AKNS equations through nonlocal symmetry reductions on the potential …

The paper aims to generate nonlocal integrable nonlinear Schrödinger hierarchies of type (−
λ, λ) by imposing two nonlocal matrix restrictions of the AKNS matrix characteristic-value …

We conduct two nonlocal group reductions of the AKNS matrix spectral problems to
generate a class of nonlocal reverse-spacetime integrable mKdV equations. One reduction …

The aim of this paper is to study vector nonlocal reverse-time NLS (nonlinear Schrödinger)
equations and present a binary Darboux transformation by utilizing two sets of …

We construct a class of novel reduced nonlocal reverse-spacetime integrable AKNS
equations by taking two group reductions of the AKNS matrix spectral problems of arbitrary …

A novel kind of reduced integrable matrix mKdV equations is generated from a group
reduction replacing the spectral parameter λ with− λ in the matrix AKNS spectral problems …
