QUATERNIONIC INTEGRABLE SYSTEMS [PDF]

open access: yesSymmetry and Perturbation Theory, 2003
Standard (Arnold-Liouville) integrable systems are intimately related to complex rotations. One can define a generalization of these, sharing many of their properties, where complex rotations are replaced by quaternionic ones. Actually this extension is not limited to the integrable case: one can define a generalization of Hamilton dynamics based on ...

Neural systems integration [PDF]

open access: yesNeurocomputing, 2004
A need is identified to build models of the central nervous system that are semi-complete, applied within multiple contexts to multiple tasks, using methodologies that span multiple levels of abstraction. The issues and constraints in building such models are discussed with respect to completeness, validation, cost, scalability and robustness.

System Integrated Information

open access: yesEntropy, 2023
Integrated information theory (IIT) starts from consciousness itself and identifies a set of properties (axioms) that are true of every conceivable experience. The axioms are translated into a set of postulates about the substrate of consciousness (called a complex), which are then used to formulate a mathematical framework for assessing both the ...

Integrability on the Master Space [PDF]

open access: yes, 2012
It has been recently shown that every SCFT living on D3 branes at a toric Calabi-Yau singularity surprisingly also describes a complete integrable system.

Averaging method for systems with separatrix crossing [PDF]

open access: yes, 2017
The averaging method provides a powerful tool for studying evolution in near-integrable systems. Existence of separatrices in the phase space of the underlying integrable system is an obstacle for application of standard results that justify using of ...

Adelic integrable systems [PDF]

open access: yesJournal of Mathematical Physics, 1995
Incorporating the zonal spherical function (zsf) problems on real and p-adic hyperbolic planes into a Zakharov–Shabat integrable system setting, we find a wide class of integrable evolutions that respect the number-theoretic properties of the zsf problem.

A Complex Integrable Hierarchy and Its Hamiltonian Structure for Integrable Couplings of WKI Soliton Hierarchy

open access: yesAbstract and Applied Analysis, 2014
We generate complex integrable couplings from zero curvature equations associated with matrix spectral problems in this paper. A direct application to the WKI spectral problem leads to a novel soliton equation hierarchy of integrable coupling system ...

Nonlocal PT-Symmetric Integrable Equations of Fourth-Order Associated with so(3, ℝ)

open access: yesMathematics, 2021
The paper aims to construct nonlocal PT-symmetric integrable equations of fourth-order, from nonlocal integrable reductions of a fourth-order integrable system associated with the Lie algebra so(3,R). The nonlocalities involved are reverse-space, reverse-

A Hierarchy of Discrete Integrable Coupling System with Self-Consistent Sources

open access: yesJournal of Applied Mathematics, 2014
Integrable coupling system of a lattice soliton equation hierarchy is deduced. The Hamiltonian structure of the integrable coupling is constructed by using the discrete quadratic-form identity.

Chaotic string motion in a near pp-wave limit

open access: yesJournal of High Energy Physics, 2023
We revisit classical string motion in a near pp-wave limit of AdS5 × S5. It is known that the Toda lattice models are integrable. But if the exponential potential is truncated at finite order, then the system may become non-integrable.
