A Discrete Weighted Helmholtz Decomposition and Applications to Non-overlapping Domain Decomposition for Saddle-point Maxwell Systems with Jumps in Coefficients
Maxwell's equations N秂d秂lec 痭ite elements weighted Helmholtz decom-position domain decomposition saddle-point system, preconditioners, condition number
2012/8/8
We shall establish a discrete weighted Helmholtz decomposition in edge element
spaces, which is stable uniformly with respect to the jumps in the discontinuous weight
function. The stable decomposit...
Supports of Weighted Equilibrium Measures and Examples
Weighted Pluripotential Theory Extremal Measures
2011/1/17
We analyze the supports of weighted equilibrium measures in Cn. We give explicit examples of families of compact sets which arise as the support of a weighted equilibrium measure for some admissible w...
Compactness of the $\bar\partial $ - Neumann operator on weighted $(0,q)$- forms
@-Neumann problem Sobolev spaces compactness
2011/2/24
As an application of a new characterization of compactness of the @-Neumann operator we derive a sufficient condition for compactness of the @- Neumann operator on (0, q)-forms in weighted L2-spaces o...
Compactness properties of weighted summation operators on trees - the critical case
Metrics on trees operators on trees weighted summation operators
2010/12/6
The aim of this paper is to provide upper bounds for the entropy numbers of summation
operators on trees in a critical case. In a recent paper [10] we elaborated a framework of
weighted summation op...

Isomorphism among families of weighted K3 hypersurfaces
Isomorphism families weighted K3 hypersurfaces
2010/12/6
Some of the 95 families of weighted K3 hypersurfaces have been known to have the isometric lattice polarizations. It is shown that weighted K3 hyper-surfaces in such families are to one-to-one corresp...
Pullbacks of Siegel Eisenstein Series and Weighted Averages of Critical $L$-values
Special values of L-functions pullbacks of Eisenstein series
2010/11/29
In this paper we obtain a weighted average formula for special values of L-functions attached to normalized elliptic modular forms of weight k and full level. These results are obtained by studying th...

2007/12/12
We develop and analyze a first-order system least-squares spectral
method for the second-order elliptic boundary value problem with
variable coefficients. We first analyze the Chebyshev weighted nor...
