Lax pair tensors and integrable spacetimes [PDF]

open access: yesGeneral Relativity and Gravitation, 1997
The use of Lax pair tensors as a unifying framework for Killing tensors of arbitrary rank is discussed. Some properties of the tensorial Lax pair formulation are stated.

Lax pair tensors in arbitrary dimensions [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1998
A recipe is presented for obtaining Lax tensors for any n-dimensional Hamiltonian system admitting a Lax representation of dimension n. Our approach is to use the Jacobi geometry and coupling-constant metamorphosis to obtain a geometric Lax formulation ...

Time-like boundary conditions in the NLS model

open access: yesNuclear Physics B, 2019
We focus on the non-linear Schrödinger model and we extend the notion of space-time dualities in the presence of integrable time-like boundary conditions.

Group similarity solutions of (2 + 1) Boiti-Leon-Manna-Pempinelli Lax pair

open access: yesAin Shams Engineering Journal, 2014
In this paper, a two parameter group transformation is applied to the Lax pair of a (2+1) Boiti–Leon–Manna–Pempinelli (BMLP). Three similarity variables are derived.

The Lax pair for the fermionic Bazhanov-Stroganov R-operator

open access: yesPhysics Letters B, 2021
We derive the Lax connection of the free fermion model on a lattice starting from the fermionic formulation of Bazhanov-Stroganov's three-parameter elliptic parametrization for the R-operator.

Assessing vowel effects on voice quality, and voice quality effects on the respiratory system [PDF]

open access: yesJASA Express Letters, 2021
This study assesses (a) effects of vowel height and tense-lax status on the laryngeal closed quotient (CQ) and (b) whether respiratory volume changes vary with differences in CQ.

GEOMETRIZATION OF THE LAX PAIR TENSORS [PDF]

open access: yesModern Physics Letters A, 2000
The tensorial form of the Lax pair equations are given in a compact and geometrically transparent form in the presence of Cartan's torsion tensor. Three-dimensional space–times admitting Lax tensors are analyzed in detail. Solutions to Lax tensor equations include interesting examples as separable coordinates and the Toda lattice.

Geometry of coupled dispersionless equations with Mannheim curves

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
In this paper, a special kind of curve pair associated with each other by the linear dependency between the principal normal vector of the first curve (called Mannheim curve) and the binormal vector of the second curve (called Mannheim partner curve) is ...

Lax Pairs for Linear Hamiltonian Systems [PDF]

open access: yesSiberian Mathematical Journal, 2019
In the paper Lax pairs for linear Hamiltonian systems of differential equations are constructed. In particular, Gr bner bases are used for the computations. It is proved that the maps which appear in the construction of Lax pairs are Poisson. Various properties of first integrals of the system which are obtained from the Lax pairs are investigated.
