Learning Theory for Dynamical Systems

open access: yesSIAM Journal on Applied Dynamical Systems, 2023
The task of modelling and forecasting a dynamical system is one of the oldest problems, and it remains challenging. Broadly, this task has two subtasks - extracting the full dynamical information from a partial observation; and then explicitly learning the dynamics from this information.

An Overview of the Hamilton–Jacobi Theory: the Classical and Geometrical Approaches and Some Extensions and Applications

open access: yesMathematics, 2021
This work is devoted to review the modern geometric description of the Lagrangian and Hamiltonian formalisms of the Hamilton–Jacobi theory. The relation with the “classical” Hamiltonian approach using canonical transformations is also analyzed ...

Dimension reduction of dynamical systems on networks with leading and non-leading eigenvectors of adjacency matrices

open access: yesPhysical Review Research, 2022
Dimension reduction techniques for dynamical systems on networks are considered to promote our understanding of the original high-dimensional dynamics.

Dark Type Dynamical Systems: The Integrability Algorithm and Applications

open access: yesAlgorithms, 2022
Based on a devised gradient-holonomic integrability testing algorithm, we analyze a class of dark type nonlinear dynamical systems on spatially one-dimensional functional manifolds possessing hidden symmetry properties and allowing their linearization on

Time-averaging axion-like interacting scalar fields models

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this paper, we study a cosmological model inspired in the axionic matter with two canonical scalar fields $$\phi _1$$ ϕ 1 and $$\phi _2$$ ϕ 2 interacting through a term added to its potential. Introducing novel dynamical variables, and a dimensionless

On the birth of limit cycles for non-smooth dynamical systems [PDF]

open access: yes, 2014
The main objective of this work is to develop, via Brower degree theory and regularization theory, a variation of the classical averaging method for detecting limit cycles of certain piecewise continuous dynamical systems.

Data-driven prediction in dynamical systems: recent developments

open access: yesPhilosophical Transactions of the Royal Society A, 2022
In recent years, we have witnessed a significant shift toward ever-more complex and ever-larger-scale systems in the majority of the grand societal challenges tackled in applied sciences. The need to comprehend and predict the dynamics of complex systems

Stack- and Queue-like Dynamics in Recurrent Neural Networks [PDF]

open access: yes, 2005
What dynamics do simple recurrent networks (SRNs) develop to represent stack-like and queue-like memories? SRNs have been widely used as models in cognitive science.

Double field theory at SL(2) angles

open access: yesJournal of High Energy Physics, 2017
An extended field theory is presented that captures the full SL(2) × O(6, 6 + n) duality group of four-dimensional half-maximal supergravities. The theory has section constraints whose two inequivalent solutions correspond to minimal D = 10 supergravity ...

Synchronization of dissipative dynamical systems driven by non-Gaussian Lévy noises [PDF]

open access: yes, 2009
Dynamical systems driven by Gaussian noises have been considered extensively in modeling, simulation, and theory. However, complex systems in engineering and science are often subject to non-Gaussian fluctuations or uncertainties.
