Discrete time from quantum physics [PDF]
Nuclear Physics B, 1994 't Hooft has recently developed a discretisation of (2+1) gravity which has a multiple-valued Hamiltonian and which therefore admits quantum time evolution only in discrete steps. In this paper, we describe several models in the continuum with single-valued equations of motion in classical physics, but with multiple-valued Hamiltonians.

Mathematics, 2021 This paper compares two discrete-time single-server queueing models with two queues. In both models, the server is available to a queue with probability 1/2 at each service opportunity.

Design of a Discrete-time Sliding Mode Controller for Nonlinear Affine Systems based on Disturbance Estimation [PDF]
Journal of Electrical and Computer Engineering Innovations, 2017 Background and Objectives: Nowadays, because of accuracy, speed, cost, and flexibility of digital control laws, control systems are implemented by computers, microprocessors or DSP chips.

Global stability of discrete-time non-linear systems with descriptor standard and fractional positive linear parts and scalar feedbacks [PDF]
Archives of Control Sciences, 2020 The global stability of discrete-time nonlinear systems with descriptor positive linear parts and positive scalar feedbacks is addressed. Sufficient conditions for the global stability of standard and fractional nonlinear systems are established.

Axioms, 2022 A discrete modified Leslie–Gower prey-predator model considering the effect of fear on prey species is proposed and studied in this paper. First, we discuss the existence of equilibria and the local stability of the model.

International Mathematics Research Notices, 2013 We introduce two new exactly solvable (stochastic) interacting particle systems which are discrete time versions of q-TASEP. We call these geometric and Bernoulli discrete time q-TASEP. We obtain concise formulas for expectations of a large enough class of observables of the systems to completely characterize their fixed time distributions when started

Dissipative Prethermal Discrete Time Crystal
Physical Review Letters, 2023 An ergodic system subjected to an external periodic drive will be generically heated to infinite temperature. However, if the applied frequency is larger than the typical energy scale of the local Hamiltonian, this heating stops during a prethermal period that extends exponentially with the frequency.
