Symplectic Homogenization

open access: yesJournal de l’École polytechnique — Mathématiques, 2022
Let H(q,p) be a Hamiltonian on T * T n . Under suitable assumptions on H, we show that the sequence (H k ) k≥1 defined by H k (q,p)=H(kq,p) converges in the γ-topology—defined in [Vit92]—to an integrable continuous Hamiltonian H ¯(p). This is extended to the case of non-autonomous Hamiltonians, and the more general setting in which only some of the ...

Homogeneous and Multiphase Analysis of Nanofluids Containing Nonspherical MWCNT and GNP Nanoparticles Considering the Influence of Interfacial Layering

open access: yesNanomaterials, 2021
The practical implication of nanofluids is essentially dependent on their accurate modelling, particularly in comparison with the high cost of experimental investigations, yet the accuracy of different computational approaches to simulate nanofluids ...

Homomorphism–homogeneous graphs [PDF]

open access: yesJournal of Graph Theory, 2010
AbstractWe answer two open questions posed by Cameron and Nesetril concerning homomorphism–homogeneous graphs. In particular we show, by giving a characterization of these graphs, that extendability to monomorphism or to homomorphism leads to the same class of graphs when defining homomorphism–homogeneity.

Homogeneous Cotton solitons

open access: yes, 2013
Left-invariant Cotton solitons on homogeneous manifolds are determined. Moreover, algebraic Cotton solitons are studied providing examples of non-invariant Cotton solitons, both in the Riemannian and Lorentzian homogeneous ...

Are cryptocurrencies homogeneous? [PDF]

open access: yesEuropean Financial Management, 2019
AbstractThis article investigates if cryptocurrencies returns' are similarly affected by a selection of demand‐ and supply‐side determinants. Homogeneity among cryptocurrencies is tested via a least absolute shrinkage and selection operator (LASSO) model where determinants of Bitcoin returns are applied to a sample of 12 cryptocurrencies.
