Jackknife Empirical Likelihood Method for Some Risk Measures and Related Quantities
Confidence interval jackknife empirical likelihood risk measure
2016/1/20
Quantifying risks is of importance in insurance. In this paper, we employ the jackknife empirical likelihood method to construct confidence intervals for some risk measures and related quantities stud...
Lp estimates for quantities advected by a compressible flow
Lp estimates quantities advected compressible flow
2015/10/15
We consider the evolution of a quantity advected by a compressible flow and subject to diffusion. When this quantity is scalar it can be, for instance, the temperature of the flow or the concentration...
Non-Noether Symmetries and Lutzky Conserved Quantities for Mechanico-Electrical Systems
Mechanico-electrical system Non-Noether symmetry Lutzky conserved quantity
2012/8/7
We apply the non-Noether symmetry theory for mechanical systems to Lagrange–Maxwell mechanico-electrical systems. For these systems,
we derive the Lutzky conserved quantities from the corresponding e...
Asymptotics of spectral quantities of Schrodinger operators
Asymptotics spectral quantities Schrodinger operators
2011/9/19
Abstract: In this paper we provide new asymptotic estimates of the Floquet exponents of Schr\"odinger operators on the circle. By the same techniques, known asymptotic estimates of various others spec...
Current response, structure factor and hydrodynamic quantities of a two- and three-dimensional Fermi gas from the operator product expansion
Current response structure factor
2011/7/21
We apply the operator product expansion to determine the asymptotic form of the current response of a Fermi gas in two and three dimensions.
Modular Equations and Evaluations of Ramanujan Quantities
Ramanujan Continued Fractions Quantities Modular Equations Derivatives Evaluations
2011/9/5
Abstract: In this article we continue a previous work, in which we have generalized the Rogers Ramanujan continued fraction (RR) introducing what we call, the Ramanujan-Quantities (RQ). In the present...
Conserved quantities and generalized solutions of the ultradiscrete KdV equation
Conserved quantities generalized solutions ultradiscrete KdV equation
2011/2/22
We construct generalized solutions to the ultradiscrete KdV equation,including the so-called negative solition solutions. The method is based on the ultradiscretization of soliton solutions to the dis...
(Non)Invariance of dynamical quantities for orbit equivalent flows
Dynamical Systems (math.DS) General Relativity and Quantum Cosmology (gr-qc) Chaotic Dynamics (nlin.CD)
2010/11/10
We study how dynamical quantities such as Lyapunov exponents, metric entropy, topological pressure, recurrence rates, and dimension-like characteristics change under a time reparameterization of a dyn...
After trees die:quantities and determinants of necromass across Amazonia
trees die quantities determinants necromass across Amazonia
2010/1/20
The Amazon basin, one of the most substantial biomass carbon pools on earth, is characterised by strong macroecological gradients in biomass, mortality rates, and wood density from west to east. These...

Effects of the Size of Cosmological N-body Simulations on Physical Quantities– II：Halo Formation and Destruction Rate
Large scale structure of Universe N-body simulations galaxies
2009/5/12
In this study we show how errors due to finite box size
affect formation and the destruction rate for haloes in cosmological N-body
simulations. In an earlier study we gave an analytic prescription ...
We construct and analyze a family of semi-discretized difference
schemes with two parameters for the Korteweg-de Vries (KdV) equation.
The scheme possesses the first four near-conserved quantities f...
In this paper, we present a new semi-discrete difference scheme for the KdV equation, which possesses the first four nearconserved quatities. The scheme is better than the past one given in [4], becau...
