Forbidden Subgraphs for Existences of (Connected) 2-Factors of a Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2023
Clearly, having a 2-factor in a graph is a necessary condition for a graph to be hamiltonian, while having an even factor in graph is a necessary condition for a graph to have a 2-factor.

Hamiltonian structure of Hamiltonian chaos [PDF]

open access: yesPhysics Letters A, 1997
From a kinematical point of view, the geometrical information of hamiltonian chaos is given by the (un)stable directions, while the dynamical information is given by the Lyapunov exponents. The finite time Lyapunov exponents are of particular importance in physics.

Thermal buckling and postbuckling of functionally graded multilayer GPL-reinforced composite beams on nonlinear elastic foundations

open access: yesHeliyon, 2023
Under the influence of axial forces and uniform temperature variations, the thermal buckling and postbuckling of composite beams reinforced of functionally graded multilayer graphene platelets (GPLs) resting on nonlinear elastic foundations are examined.

The Hamiltonian Syllogistic [PDF]

open access: yesJournal of Logic, Language and Information, 2011
This paper undertakes a re-examination of Sir William Hamilton's doctrine of the quantification of the predicate. Hamilton's doctrine comprises two theses. First, the predicates of traditional syllogistic sentence-forms contain implicit existential quantifiers, so that, for example, "All p are q" is to be understood as "All p are some q". Second, these

Research on Flight Collision Avoidance Control on The Sun-Earth Libration Points Based on Barrier Theory [PDF]

open access: yesXibei Gongye Daxue Xuebao, 2018
In the spacecraft formation task, a spacecraft failure or formation of the mission to change the need for reconstruction of the formation. In the process of reconstruction, how to carry out spacecraft anti-collision has been widespread concern.

On degree-sequence characterization and the extremal number of edges for various Hamiltonian properties under fault tolerance [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
Assume that $n, \delta ,k$ are integers with $0 \leq k < \delta < n$. Given a graph $G=(V,E)$ with $|V|=n$. The symbol $G-F, F \subseteq V$, denotes the graph with $V(G-F)=V-F$, and $E(G-F)$ obtained by $E$ after deleting the edges with at least one ...

SOME PROPERTIES ON COPRIME GRAPH OF GENERALIZED QUATERNION GROUPS

open access: yesBarekeng, 2023
A coprime graph is a representation of finite groups on graphs by defining the vertex graph as an element in a group and two vertices adjacent to each other's if and only if the order of the two elements is coprime.

Hamiltonians for curves [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2002
We examine the equilibrium conditions of a curve in space when a local energy penalty is associated with its extrinsic geometrical state characterized by its curvature and torsion. To do this we tailor the theory of deformations to the Frenet-Serret frame of the curve.

Smooth-Switching Control of Robot-Based Permanent-Magnet Synchronous Motors via Port-Controlled Hamiltonian and Feedback Linearization

open access: yesEnergies, 2020
To solve the contradiction between dynamic performance and steady-state performance of the robot system, a smooth-switching control strategy is proposed.
