Interest Rate Based on The Lie Group SO(3) in the Evidence of Chaos
Mathematics, 2022 This paper aims to test the structure of interest rates during the period from 1 September 1981 to 28 December 2020 by using Lie algebras and groups. The selected period experienced substantial events impacting interest rates, such as the economic crisis,

Darboux transformation for the NLS equation [PDF]
AIP Conference Proceedings, 2010 We analyze a certain class of integral equations associated with Marchenko equations and Gel’fand‐Levitan equations. Such integral equations arise through a Fourier transformation on various ordinary differential equations involving a spectral parameter.

The Lattice Sine-Gordon Equation as a Superposition Formula for an NLS-Type System [PDF]
, 2021 We treat the lattice sine-Gordon equation and two of its generalised symmetries as a compatible system. Elimination of shifts from the two symmetries of the lattice sine-Gordon equation yields an integrable NLS-type system.

Scattering-like phenomena of the periodic defocusing nls equation [PDF]
, 2017 In this paper we prove approximation properties of the solutions of the defocusing NLS equation on the circle by nearly linear flows. In addition we show that spatially periodic solutions of the defocusing NLS equation evolving in fractional Sobolev ...

Phase portraits and new exact traveling wave solutions of the (2+1)-dimensional Hirota system
Results in Physics, 2023 In this paper, we investigate the (2+1)-dimensional Hirota system of equations, which is essential for modeling physical events since it contains the NLS equation and the cmKdV equation. We apply the Jacobi elliptic function method to obtain new results.

Non-commutative NLS-type hierarchies: Dressing & solutions
Nuclear Physics B, 2019 We consider the generalized matrix non-linear Schrödinger (NLS) hierarchy. By employing the universal Darboux-dressing scheme we derive solutions for the hierarchy of integrable PDEs via solutions of the matrix Gelfand-Levitan-Marchenko equation, and we ...
