On well-posedness of semilinear Rayleigh-Stokes problem with fractional derivative on ℝN

open access: yesAdvances in Nonlinear Analysis, 2021
We are devoted to the study of a semilinear time fractional Rayleigh-Stokes problem on ℝN, which is derived from a non-Newtonain fluid for a generalized second grade fluid with Riemann-Liouville fractional derivative.

Nonlocal PT-symmetric integrable equations and related Riemann–Hilbert problems

open access: yesPartial Differential Equations in Applied Mathematics, 2021
We aim to discuss about how to construct and classify nonlocal PT-symmetric integrable equations via nonlocal group reductions of matrix spectral problems.

Integrable nonlinear equations and Liouville's theorem, I [PDF]

open access: yesCommunications in Mathematical Physics, 1981
A symplectic structure is constructed and the Liouville integration carried out for a stationary Lax equation [L, P]=0, whereL is a scalar differential operator of an arbitrary order.nth order operators are included into the variety of first-order matrix operators, and properties of this inclusion are studied.

Bifurcation Diagram of the Model of a Lagrange Top with a Vibrating Suspension Point

open access: yesMathematics, 2023
The article considers a model system that describes a dynamically symmetric rigid body in the Lagrange case with a suspension point that performs high-frequency oscillations. This system, reduced to axes rigidly connected to the body, after the averaging

Liouville integrable binomial Hamiltonian system

open access: yesJournal of Physics: Conference Series, 2023
Abstract In this study, we work on a novel Hamiltonian system which is Liouville integrable. In the integrable Hamiltonian model, conserved currents can be represented as Binomial polynomials in which each order corresponds to the integral of motion of the system.

Explicit Solutions and Conservation Laws for a New Integrable Lattice Hierarchy

open access: yesComplexity, 2019
An integrable lattice hierarchy is derived on the basis of a new matrix spectral problem. Then, some properties of this hierarchy are shown, such as the Liouville integrability, the bi-Hamiltonian structure, and infinitely many conservation laws.
