The nonlinear Schr\"odinger equation with forcing involving products of eigenfunctions [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics, 2022
We elaborate on a new methodology, which starting with an integrable evolution equation in one spatial dimension, constructs an integrable forced version of this equation.

The Tacnode Riemann–Hilbert Problem [PDF]

open access: yes, 2014
The tacnode Riemann–Hilbert problem is a 4x4 matrix-valued RH problem that appears in the description of the local behavior of two touching groups of nonintersecting Brownian motions.

The Prolongation Structure of the Modified Nonlinear Schrödinger Equation and Its Initial-Boundary Value Problem on the Half Line via the Riemann-Hilbert Approach

open access: yesMathematics, 2019
In this paper, the Lax pair of the modified nonlinear Schrödinger equation (mNLS) is derived by means of the prolongation structure theory. Based on the obtained Lax pair, the mNLS equation on the half line is analyzed with the assistance of Fokas ...

Quantum periods and TBA equations for N=2 SU(2) Nf = 2 SQCD with flavor symmetry

open access: yesPhysics Letters B, 2021
We apply the exact WKB analysis to the quantum Seiberg-Witten curve for 4-dimensional N=2 SU(2) Nf=2 SQCD with the flavor symmetry. The discontinuity and the asymptotic behavior of the quantum periods define a Riemann-Hilbert problem.

Large-x Analysis of an Operator-Valued Riemann–Hilbert Problem [PDF]

open access: yes, 2016
International audienceThe purpose of this paper is to push forward the theory of operator-valued Riemann-Hilbert problems and demonstrate their effectiveness in respect to the implementation of a non-linear steepest descent method a la Deift-Zhou.

Riemann-Hilbert problem associated with Angelesco systems [PDF]

open access: yes, 2009
Angelesco systems of measures with Jacobi-type weights are considered. For such systems, strong asymptotics for the related multiple orthogonal polynomials are found as well as the Szego-type functions.

The N-soliton solutions of the n-component generalized Sasa-Satsuma system: Riemann-Hilbert method

open access: yesNuclear Physics B
Using the Riemann-Hilbert method, the paper systematically investigates the n-component generalized Sasa-Satsuma system. By utilizing the Tu scheme, we systematically construct the n-component generalized Sasa-Satsuma integrable hierarchy, and obtain the

Long-time asymptotic behavior for the Hermitian symmetric space derivative nonlinear Schrödinger equation

open access: yesAdvanced Nonlinear Studies
Resorting to the spectral analysis of the 4 × 4 matrix spectral problem, we construct a 4 × 4 matrix Riemann–Hilbert problem to solve the initial value problem for the Hermitian symmetric space derivative nonlinear Schrödinger equation.

Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...
