Flatness and Submersivity of Discrete-Time Dynamical Systems [PDF]
IEEE Control Systems Letters, 2020 This letter addresses flatness of discrete-time systems called difference flatness. A definition of flatness, that encompasses the standard ones, in particular backward and forward difference flatness, is introduced. It also allows to cope with systems which are not necessarily controllable or submersive.

O-Minimal Invariants for Discrete-Time Dynamical Systems [PDF]
ACM Transactions on Computational Logic, 2022 Termination analysis of linear loops plays a key rôle in several areas of computer science, including program verification and abstract interpretation. Already for the simplest variants of linear loops the question of termination relates to deep open problems in number theory, such as the decidability of the Skolem and Positivity Problems ...

Time is a discrete dynamical system [PDF]
, 2021 We conjecture that quantum vacuum operates its discrete dynamics in a superposition of a class of iterating functions such that each physical system operates within a distinct function.

Dynamics of Neural Systems with Discrete and Distributed Time Delays [PDF]
SIAM Journal on Applied Dynamical Systems, 2015 Summary: In real-world systems, interactions between elements do not happen instantaneously, due to the time required for a signal to propagate, reaction times of individual elements, and so forth. Moreover, time delays are normally nonconstant and may vary with time. This means that it is vital to introduce time delays in any realistic model of neural

Dynamics of Discrete Time Systems with a Hysteresis Stop Operator [PDF]
SIAM Journal on Applied Dynamical Systems, 2017 We consider a piecewise linear two-dimensional dynamical system that couples a linear equation with the so-called stop operator. Global dynamics and bifurcations of this system are studied depending on two parameters. The system is motivated by modifications to general-equilibrium macroeconomic models that attempt to capture the frictions and memory ...

Global dynamical properties of two discrete-time exponential systems
Journal of Taibah University for Science, 2019 We explore the global dynamics of following three directional discrete-time exponential systems of difference equations: \[{x_{n + 1}} = \frac{{{\alpha _{19}} + {\beta _{19 }}{e^{ - {y_n}}}}}{{{\gamma _{19}} + {z_{n - 1}}}},\,\quad {y_{n + 1}} = \frac{{{\

Time-delayed impulsive control for discrete-time nonlinear systems with actuator saturation
Nonlinear Analysis, 2019 This paper focuses on the problem of time-delayed impulsive control with actuator saturation for discrete-time dynamical systems. By establishing a delayed impulsive difference inequality, combining with convex analysis and inequality techniques, some ...

Another New Solvable Many-Body Model of Goldfish Type
Symmetry, Integrability and Geometry: Methods and Applications, 2012 A new solvable many-body problem is identified. It is characterized by nonlinear Newtonian equations of motion (''acceleration equal force'') featuring one-body and two-body velocity-dependent forces ''of goldfish type'' which determine the motion ofan ...
