Web12 de abr. de 2024 · An on-chip integrated visible microlaser is a core unit of visible-light communication and information-processing systems and has four requirements: robustness against fabrication errors, a compressible linewidth, a reducible threshold, and in-plane emission with output light directly entering signal waveguides and photonic circuits ( 10, … Web1 de jun. de 2005 · The hamiltonian index of a graph G is the smallest integer k such that the k -th iterated line graph of G is hamiltonian. We first show that, with one exceptional case, adding an edge to a graph cannot increase its hamiltonian index.

Web6 de jan. de 2009 · The Hamiltonian Index h(G) of G is the smallest r such that Lr(G) has a Hamiltonian cycle [Chartrand, 1968]. Checking if h(G)=k is NP-hard for any fixed integer … WebIn recent years, the Morse Index has been extensively used by many scientists. In order to study the convex Hamiltonian systems Ekeland used a Dual form of the least action principle, Morse theory an how is long sighted caused
A simple upper bound for the hamiltonian index of a graph
Web4 de nov. de 2024 · Index theory revealed its outstanding role in the study of periodic orbits of Hamiltonian systems and the dynamical consequences of this theory are enormous. Although the index theory in the periodic case is well-established, very few results are known in the case of homoclinic orbits of Hamiltonian systems. WebFor a Hamiltonian system, in which the Hamiltonian is assumed to have an asymptotically linear gradient, the existence of nontrivial periodic solutions is proved under the assumption that the linearized operators have distinct Maslov indices at 0 and at infinity. Both the linearized operators may be degenerate. In particular, the results cover the “strong … WebThe easiest way is to define a new command \hatH: \documentclass {article} \newcommand* {\hatH} {\hat {\mathcal {H}}} \begin {document} \ [ \hatH \] \end {document} A redefinition of \hat is far more complicate, because of TeX rules in math. \hat expands to \mathaccent that does not parse its base as "argument" but as . how is long term capital gains figured
