Gyroharmonic Analysis on Relativistic Gyrogroups
Einstein, M"{o}bius, and Proper Velocity gyrogroups are relativistic gyrogroups that appear as three different realizations of the proper Lorentz group in the real Minkowski space-time $bkR^{n,1}.$ Using the gyrolanguage we study their gyroharmonic analysis. Although there is an algebraic gyroisomorphism between the three models we show that there are some differences between them. Our...
متن کاملContraction Degeneracy on Cographs
The contraction degeneracy of a graph G is the maximum minimum degree of G′ over all minors G′ of G. The corresponding decision problem is known to be NP -complete. In this paper, we present a dynamic programming approach for computing the contraction degeneracy of cographs.
متن کاملOn Breaking Cosmic Degeneracy
It has been argued that the power spectrum of the anisotropies in the Cosmic Microwave Background (CMB) may be effectively degenerate, namely that the observable spectrum does not determine a unique set of cosmological parameters. We describe the physical origin of this degeneracy and show that at small angular scales it is broken by gravitational lensing: effectively degenerate spectra become ...
متن کاملPropagation of Electrostatic Solitary Wave Structures in Dense Astrophysical Plasma: Effects of Relativistic Drifts & Relativistic Degeneracy Pressure
Analytical and numerical studies are presented for electron acoustic solitary wave structure in relativistic degenerate two-component unmagnetized astrophysical plasma. The existence of a wave mode of pure quantum origin is predicted. The effect of various plasma parameters on the conditions of existence and properties of solitary wave is investigated. It is shown that depending on the values o...
متن کاملA Note on Contraction Degeneracy
The parameter contraction degeneracy — the maximum minimum degree over all minors of a graph — is a treewidth lower bound and was first defined in [3]. In experiments it was shown that this lower bound improves upon other treewidth lower bounds [3]. In this note, we examine some relationships between the contraction degeneracy and connected components of a graph, blocks of a graph and the genus...
