Mathematical Structure of Discrete Space-time [PDF]
arXiv, 2009 In this letter we briefly investigate the mathematical structure of space-time in the framework of discretization. It is shown that the discreteness of space-time may result in a new mechanical system which differ from the usual quantum mechanics (QM).

On minimum intersections of certain secondary dominating sets in graphs [PDF]
Opuscula Mathematica, 2023 In this paper we consider secondary dominating sets, also named as \((1,k)\)-dominating sets, introduced by Hedetniemi et al. in 2008. In particular, we study intersections of the \((1,1)\)-dominating sets and proper \((1,2)\)-dominating sets.

$L^p$-$L^q$ Boundedness of Spectral Multipliers of the Anharmonic Oscillator
Comptes Rendus. Mathématique, 2022 In this note we study the $L^p-L^q$ boundedness of Fourier multipliers of anharmonic oscillators, and as a consequence also of spectral multipliers, for the range ...

Decomposing 10-Regular Graphs into Paths of Length 5
Discussiones Mathematicae Graph Theory, 2022 Let G be a 10-regular graph which does not contain any 4-cycles. In this paper, we prove that G can be decomposed into paths of length 5, such that every vertex is a terminal of exactly two paths.

Time-stage driven pathfinding framework for optimized medical treatments
Cogent Engineering, 2023 Coming up with the correct patient-specific treatment procedure is a non-trivial task. One of the main challenges is that the problem is combinatorial, and each treatment can be followed by numerous treatments.

Local irregularity conjecture for 2-multigraphs versus cacti [PDF]
Opuscula Mathematica, 2023 A multigraph is locally irregular if the degrees of the end-vertices of every multiedge are distinct. The locally irregular coloring is an edge coloring of a multigraph \(G\) such that every color induces a locally irregular submultigraph of \(G\).

IEEE Access, 2020 In addition to wirelength and area, modern floorplans need to consider various constraints such as fixed-outline. To handle the fixed-outline floorplanning optimization problem efficiently, we propose an improved simulated annealing (SA) algorithm, which

, 2022 In this volume, the authors present a self-contained introduction to discrete mathematics – the science of finite and countably infinite structures. In addition to taking a theoretical approach, they also include many practical exercises. The text covers a broad range of topics such as propositional logic, set theory as well as detailed treatments of ...
