Method for Obtaining Coefficients of Powers of Multivariate Generating Functions

open access: yesMathematics, 2023
There are several general concepts that allow obtaining explicit formulas for the coefficients of generating functions in one variable by using their powers. One such concept is the application of compositae of generating functions.

Robust Combinatorial Optimization with Locally Budgeted Uncertainty

open access: yesOpen Journal of Mathematical Optimization, 2021
Budgeted uncertainty sets have been established as a major influence on uncertainty modeling for robust optimization problems. A drawback of such sets is that the budget constraint only restricts the global amount of cost increase that can be distributed

Elementary Cellular Automata as Invariant under Conjugation Transformation or Combination of Conjugation and Reflection Transformations, and Applications to Traffic Modeling

open access: yesMathematics, 2022
This paper develops the analysis of properties of the cellular automata class introduced by the authors. It is assumed that the set of automaton cells is finite and forms a closed lattice, and there are two states for each automaton cell.

On Consensus and Stability under Denial-of-Service Attacks

open access: yesEntropy, 2022
In the paper, discrete-time multi-agent systems under Denial-of-Service (DoS) attacks are considered. Since in the presence of DoS attacks the stability of the whole system may be disturbed, sufficient stability conditions for the multi-agent system ...

Chenciner Bifurcation Presenting a Further Degree of Degeneration

open access: yesMathematics, 2022
Chenciner bifurcation appears for some two-dimensional systems with discrete time having two independent variables. Investigated here is a special case of degeneration where the implicit function theorem cannot be used around the origin, so a new ...

Simple exponential stability criteria of linear discrete time-delay systems [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2008
In this paper, new delay-independent asymptotic and exponential stability conditions of linear discrete delay systems based on the Lyapunov-Krasovskii method have been derived.
