Interlacement in 4-regular graphs: a new approach using nonsymmetric matrices
4-regular graph circuit partition Euler system interlacement
2012/4/18
Let F be a 4-regular graph with an Euler system C. We introduce a simple way to modify the interlacement matrix of C so that every circuit partition P of F has an associated modified interlacement mat...
A note on Gaussian correlation inequalities for nonsymmetric sets
Gaussian correlation inequalities nonsymmetric sets
2010/11/23
We consider the Gaussian correlation inequality for nonsymmetric convex sets. More precisely, if $A\subset\mathbb{R}^d$ is convex and the origin $0\in A$, then for any ball $B$ centered at the origin...
A subspace shift technique for solving close-to-critical nonsymmetric algebraic Riccati equations
A subspace shift technique close-to-critical nonsymmetric algebraic Riccati equations
2010/11/11
The worst situation in computing the minimal nonnegative solution $X_*$ of a nonsymmetric algebraic Riccati equation $\mathcal R(X)=0$ associated with an M-matrix occurs when the derivative of $\math...
Regularity results for fully nonlinear integro-differential operators with nonsymmetric positive kernels
fully nonlinear integro-differential operators nonsymmetric positive kernels
2010/11/22
In this paper, we consider fully nonlinear integro-differential equations with possibly nonsymmetric kernels. We are able to find different versions of Alexandroff-Backelman-Pucci estimate correspondi...
The Wind-driven Circulation：Quasi-geostrophic Simulations and Theory for Nonsymmetric Winds
Wind-driven Circulation Quasi-geostrophic Simulations Nonsymmetric Winds
2008/12/24
Simulations of the wind-driven Ocean circulation, carded out with an eddy-resolving quasi-geostrophic numerical model, and symmetric, idealized wind forcing have a large-scale structure that is predic...
We study perturbation bound and structured condition number about the minimal nonnegative solution of nonsymmetric algebraic Riccati equation, obtaining a sharp perturbation bound and an accurate cond...
It has been observed that the residual polynomials resulted from successive restarting cycles of GMRES($m$) may differ from one another meaningfully. In this paper, it is further shown that the polyno...

Metric Nonsymmetric Theory of Gravitation: the Analogue of the Theorem of Birkhoff
Nonsymmetric Birkhoff
2010/10/13
We prove that a spherically symmetric solution of the field equations of the metric nonsymmetric theory of gravitation developed previously is necessarily static.This is the analogue of the well known...

Conservation Laws a Metric Nonsymmetric Theory of Gravitation
2010/10/15
The conservation laws associated with a previously studied metric nonsymmetric theory of gravitation are established and their physical significance is discussed. Conservation laws are obtained for th...
