Computing the split domination number of grid graphs

Indonesian Journal of Combinatorics, 2021
<p>A set <em>D</em> - <em>V</em> is a dominating set of <em>G</em> if every vertex in <em>V - D</em> is adjacent to some vertex in <em>D</em>. The dominating number γ(<em>G</em>) of <em>G</em> is the minimum cardinality of a dominating set <em>D</em> ...

Controlling numerical diffusion in solving advection-dominated transport problems

Journal of Numerical Analysis and Approximation Theory
Numerical schemes for advection-dominated transport problems are are evaluated in a comparative study. Explicit and implicit finite difference methods are analyzed together with a global random walk algorithm in the frame of a splitting procedure.

Perturbation of the Lyapunov spectra of periodic orbits

, 2011
We describe all Lyapunov spectra that can be obtained by perturbing the derivatives along periodic orbits of a diffeomorphism. The description is expressed in terms of the finest dominated splitting and Lyapunov exponents that appear in the limit of a ...

Higgs Quark Flavor Violation: Simplified Models and Status of General Two-Higgs-Doublet Model

Journal of High Energy Physics, 2020
We study quark flavor violating interactions mediated by the Higgs boson h. We consider observables involving a third generation quark, of both the up and the down quark sectors, like h → bs and t → ch.

Dominated splittings for semi-invertible operator cocycles on Hilbert space [PDF]

, 2015
A theorem of J. Bochi and N. Gourmelon states that an invertible linear cocycle admits a dominated splitting if and only if the singular values of its iterates become separated at a uniform exponential rate.

Back Reaction of Strings in Self-Consistent String Cosmology

, 1994
We compute the string energy-momentum tensor and {\bf derive} the string equation of state from exact string dynamics in cosmological spacetimes. $1+1,~2+1$ and $D$-dimensional universes are treated for any expansion factor $R$.

Finite bias Cooper pair splitting

, 2011
In a device with a superconductor coupled to two parallel quantum dots (QDs) the electrical tunability of the QD levels can be used to exploit non-classical current correlations due to the splitting of Cooper pairs.

Magnetic ground state of Dy3+ in DyNiAl4

AIP Advances, 2017
Previously, the bulk magnetisation of polycrystalline DyNiAl4 was found to reach barely half its expected saturation value with a 9 T applied field. New inelastic neutron scattering and 161Dy-Mössbauer spectroscopy results suggest that the crystal field ...

Improved opacity expansion for medium-induced parton splitting

Journal of High Energy Physics, 2020
We present a new expansion scheme to compute the rate for parton splittings in dense and finite QCD media. In contrast to the standard opacity expansion, our expansion is performed around the harmonic oscillator whose characteristic frequency depends on ...
