Conditional Symmetries and Riemann Invariants for Hyperbolic Systems of PDEs [PDF]
This paper contains an analysis of rank-k solutions in terms of Riemann invariants, obtained from interrelations between two concepts, that of the symmetry reduction method and of the generalized method of characteristics for first order quasilinear ...

Riemann–Hilbert approach to the elastodynamic equation: half plane
We show, how the Riemann–Hilbert approach to the elastodynamic equations, which have been suggested in our preceding papers, works in the half plane case.

The Modified Coupled Hirota Equation: Riemann-Hilbert Approach and N-Soliton Solutions
The Cauchy initial value problem of the modified coupled Hirota equation is studied in the framework of Riemann-Hilbert approach. The N-soliton solutions are given in a compact form as a ratio of (N+1)×(N+1) determinant and N×N determinant, and the ...

Dark effects in $$\tilde{f}(R,P)$$ f ~ ( R , P ) gravity
In the present paper a new cosmological model is proposed by extending the Einstein–Hilbert Lagrangian with a generic functional $$\tilde{f}(R,P)$$ f ~ ( R , P ) , which depends on the scalar curvature R and a term P which encodes a possible influence ...

The “Good” Boussinesq Equation: a Riemann-Hilbert Approach
We develop an inverse scattering transform formalism for the “good” Boussinesq equation on the line. Assuming that the solution exists, we show that it can be expressed in terms of the solution of a 3 × 3 matrix Riemann-Hilbert problem.

This article combines the Riemann–Hilbert method with fractional power-law time-varying spectrum for the first time to solve a time fractional nonisospectral complex mKdV (tfniscmKdV) equation. Firstly, the tfniscmKdV equation and its associated Lax pair

A Riemann–Hilbert approach to the Heun equation [PDF]
We describe the close connection between the linear system for the sixth Painlevé equation and the general Heun equation, formulate the Riemann–Hilbert problem for the Heun functions and show how, in the case of reducible monodromy, the Riemann–Hilbert ...

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 ...

A general framework for solving Riemann-Hilbert problems\ud numerically [PDF]
A new, numerical framework for the approximation of solutions to matrix-valued Riemann-Hilbert problems is developed, based on a recent method for the homogeneous Painlev\'e II Riemann- Hilbert problem.
