Slow invariant manifolds as curvature of the flow of dynamical systems [PDF]

open access: yes, 2014
Considering trajectory curves, integral of n-dimensional dynamical systems, within the framework of Differential Geometry as curves in Euclidean n-space, it will be established in this article that the curvature of the flow, i.e.

ŽAMPA’S SYSTEMS THEORY: A COMPREHENSIVE THEORY OF MEASUREMENT IN DYNAMIC SYSTEMS [PDF]

open access: yesActa Polytechnica, 2018
The article outlines in memoriam Prof. Pavel Žampa’s concepts of system theory which enable us to devise a measurement in dynamic systems independently of the particular system behaviour. From the point of view of Žampa’s theory, terms like system time, system attributes, system link, system element, input, output, sub-systems, and state variables are ...

Dynamical Mean-Field Theory for Markovian Open Quantum Many-Body Systems

open access: yesPhysical Review X, 2021
A number of experimental platforms relevant for quantum simulations, ranging from arrays of superconducting circuits hosting correlated states of light to ultracold atoms in optical lattices in the presence of controlled dissipative processes, are ...

The precession of eccentric discs in close binaries [PDF]

open access: yes, 1999
We consider the precession rates of eccentric discs in close binaries, and compare theoretical predictions with the results of numerical disc simulations and with observed superhump periods.

Controllability of nonlinear fractional Langevin delay systems

open access: yesNonlinear Analysis, 2019
In this paper, we discuss the controllability of fractional Langevin delay dynamical systems represented by the fractional delay differential equations of order 0

On discrete-time models of network worm propagation generated by quadratic operators

open access: yesMathematical Modelling and Analysis, 2023
In this paper we consider the discrete-time dynamical systems generated by network worm propagation models based on the theory of quadratic stochastic operators(QSO).

Infinite-dimensional projected dynamics and the 1-dimensional obstacle problem

open access: yesJournal of Function Spaces and Applications, 2005
In this paper we present a direct application of the theory of infinite-dimensional projected dynamical systems (PDS) related to the well-known obstacle problem, i.e., the problem of determining the shape of an elastic string stretched over a body ...

The wind-driven ocean circulation: Applying dynamical systems theory to a climate problem

open access: yes, 2016
The large-scale, near-surface flow of the mid-latitude oceans is dominated by the presence of a larger, anticyclonic and a smaller, cyclonic gyre.

Characterization of degeneration process in combustion instability based on dynamical systems theory.

open access: yesPhysical review. E, Statistical, nonlinear, and soft matter physics, 2015
We present a detailed study on the characterization of the degeneration process in combustion instability based on dynamical systems theory. We deal with combustion instability in a lean premixed-type gas-turbine model combustor, one of the fundamentally

Global entrainment of transcriptional systems to periodic inputs. [PDF]

open access: yesPLoS Computational Biology, 2010
This paper addresses the problem of providing mathematical conditions that allow one to ensure that biological networks, such as transcriptional systems, can be globally entrained to external periodic inputs.
