휂-Ricci solitons on Lorentzian 훽-Kenmotsu manifold are considered an manifolds satisfying certain curvature Conditions, R(ξ,X).S=0, S(ξ,X).R=0, W2(ξ,X).S=0,S(ξ,X).W2=0 We proved that in β-Kenmotsu (M,φ,ξ,η,푔). Then the existence of implies M is Einstein and if Ricci tensor satisfies, then steady. If condition 휇=0, 휆=0, which shows 휆is steady

We calculate the nondegenerate bound electronic nonlinear refractive index n2 ( w1; w2) (i.e., an index change at frequency w1 due to the presence of a beam at frequency w2) in semiconductors. We calculate this nonlinearity and its disper~ sion using a Kramers-Kronig transformation on the calculated nondegenerate nonlinear absorption spectrum due to two-photon absorption, electronic Raman and o...

We study the sets of values taken by the exponents of quadratic approximation w2 and w ∗ 2 evaluated at real numbers whose sequence of partial quotients is generated by a finite automaton. Among other results, we show that these sets contain every sufficiently large rational number and also some transcendental numbers. Résumé. Nous étudions les ensembles des valeurs prises par les exposants d’a...

The question of scaling of 2MpWI and v W2 as a function of w is discussed. Scaling is verified for a large kinematic range. Also, a new scaling variable which reduces to w in the Bjorken limit is introduced which extends the scaling region. The behavior of crT and us are also discussed as a function of v and q2a Various weighted sum rules of v W2 are evaluated. (Submitted to Phys. Rev. Letters....

We apply our recently developed code for spherically symmetric, fully general relativistic (GR) Lagrangian hydrodynamics and multigroup flux-limited diffusion (MGFLD) neutrino transport to examine the effects of GR on the hydrodynamics and transport during collapse, bounce, and the critical shock reheating phase of core collapse supernovae. GR effects were examined by performing core collapse s...

Recently I.) used velocity moments of a classical kinetic equation to derive a hydrody-namic description of electron motion in a degenerate electron gas. Independently , the present authors (Theochem 501-502, 327 (2000)) used considerations arising from the Harmonic Potential Theorem (Phys. Rev. Lett. 73, 2244 (1994)) to generate a new form of high-frequency hydrodynamics for in-homogeneous deg...

Landau-Ginzburg mirror symmetry studies isomorphisms between Aand B-models, which are graded Frobenius algebras that are constructed using a weighted homogeneous polynomial W and a related symmetry group G. Given two polynomials W1, W2 with the same weights and same group G, the corresponding A-models built with (W1,G) and (W2,G) are isomorphic. Though the same result cannot hold in full genera...

© 2014, Springer-Verlag Berlin Heidelberg. In this paper we study local properties of cost and potential functions in optimal transportation. We prove that in a proper normalization process, the cost function is uniformly smooth and converges locally smoothly to a quadratic cost x · y, while the potential function converges to a quadratic function. As applications we obtain the interior W2, p e...

W develop a new local search algorithm for binary optimization problems, whose complexity and performance are explicitly controlled by a parameter Q, measuring the depth of the local search neighborhood. We show that the algorithm is pseudo-polynomial for general cost vector c, and achieves a w2/42w−15 approximation guarantee for set packing problems with exactly w ones in each column of the co...
