Law of large numbers for branching symmetric Hunt processes with measure-valued branching rates
Law of large numbers branching Hunt processes spine approach h-transform spectral gap
2016/1/26
We establish weak and strong law of large numbers for a class of branching symmetric Hunt processes with the branching rate being a smooth measure with respect to the underlying Hunt process, and the ...
MINRES-QLP: A KRYLOV SUBSPACE METHOD FOR INDEFINITE OR SINGULAR SYMMETRIC SYSTEMS
MINRES Krylov subspace method Lanczos process
2015/7/3
CG, SYMMLQ, and MINRES are Krylov subspace methods for solving symmetric
systems of linear equations. When these methods are applied to an incompatible system (that is,
a singular symmetric least-sq...
Algorithm 937: MINRES-QLP for Symmetric and Hermitian Linear Equations and Least-Squares Problems
Symmetric Hermitian Linear
2015/7/3
If the system is singular, MINRES-QLP computes the unique
minimum-length solution (also known as the pseudoinverse solution), which generally eludes MINRES. In
all cases, it overcomes a potential in...
ON THE STABILITY OF CHOLESKY FACTORIZATION FOR SYMMETRIC QUASIDEFINITE SYSTEMS*
indefinite systems symmetric quasidefinite (sqd) systems
2015/7/3
Sparse linear equations Kd r are considered, where K is a specially structured
symmetric indefinite matrix that arises in numerical optimization and elsewhere. Under certain
conditions, K is quaside...

Symmetry breaking in symmetric and asymmetric double-well potentials
Matter waves light beam the nonlinear schrodinger equation nonlinear solution attractive and nonlinear disturbances
2014/12/25
Motivated by recent experimental studies of matter waves and optical beams in double-well potentials, we study the corresponding solutions of the nonlinear Schrödinger equation. Using a Galerkin-...
Radially symmetric nonlinear states of harmonically trapped Bose-Einstein condensates
Spectrum quantum harmonic oscillator nonlinear function linear stability
2014/12/25
Starting from the spectrum of the radially symmetric quantum harmonic oscillator in two dimensions, we create a large set of nonlinear solutions. The relevant three principal branches, with nr=0,1, an...
Isothermic submanifolds of symmetric $R$-spaces
Classic theory 3 - space line surface the space of submanifolds R dollars and losses
2014/12/24
We extend the classical theory of isothermic surfaces in conformal 3-space, due to Bour, Christoffel, Darboux, Bianchi and others, to the more general context of submanifolds of symmetric $R$-spaces w...
A study on the relation between the smooth structure of a symplectic homotopy K3 surface and its symplectic symmetries is initiated. A measurement of exoticness of a symplectic homotopy K3 surface is ...
Distribution and Symmetric Distribution Regression Model for Histogram-Valued Variables

2013/4/28
Histogram-valued variables are a particular kind of variables studied in Symbolic Data Analysis where to each entity under analysis corresponds a distribution that may be represented by a histogram or...
Skew-Symmetric Distributions and Fisher Information the double sin of the skew-normal
Skew-Symmetric Distributions Fisher Information skew-normal double sin
2012/11/22
Hallin and Ley (2012) investigate and fully characterize the Fisher singularity phenomenon in univariate and multivariate families of skew-symmetric distributions. This paper proposes a refined analys...
Some Pitman Closeness Properties Pertinent to Symmetric Populations
Pitman closeness order statistics symmetric random variables estimators sample median more peaked distribution ranked set sampling median ranked set sampling
2012/9/19
In this paper, we focus on Pitman closeness probabilities when the estimators are symmetrically distributed about the unknown parameter θ. We first consider two symmetric estimatorsˆθ1andˆθ2...
Skew-symmetric distributions and Fisher information -- a tale of two densities
singular Fisher information skew-normal distributions skew-symmetric distributions skewing function symmetric kernel
2012/9/18
Skew-symmetric densities recently received much attention in the literature, giving rise to in-creasingly general families of univariate and multivariate skewed densities. Most of those families,howev...

2010/2/24
In K. Yano, Y. Yano and M. Yor (2009), limit theorems for the one-dimensional symmetric α-stable process normalized by negative (killing) Feynman-Kac functionals were studied. We consider the same pro...
