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

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...
Conservativity of Symplectic Methods for the Ablowitz-Ladik Discrete Nonlinear Schrodinger Equation
Nonlinear Schrdinger Equation Ablowitz-Ladik Model Darboux
2012/8/7
Using several kinds of Darboux transformations, we standardize the non-
canonical symplectic structure of Ablowitz-Ladik model (A-L model) of the
Nonlinear Schr膐dinger Equation (NLSE), then we emplo...

Discrete DS equation Casorati determinant Grammian determinant B腶cklund
2012/8/7
We propose a di甧rential di甧rence equation in R1 ?Z2 and study it by Hirota's bilinear
method. This equation has a singular continuum limit into a system which admits the reduction
to the Davey-Stewa...
Coherent discrete embeddings for Lagrangian and Hamiltonian systems

2011/8/25
Abstract: The general topic of the present paper is to study the conservation for some structural property of a given problem when discretising this problem. Precisely we are interested with Lagrangia...
Convergence of Inner Iterations Scheme of the Discrete Ordinate Method in Spherical Geometry
2007/12/12
In transport theory, the convergence of the inner iteration scheme to the spherical neutron transport equation has been an open problem. In this paper, the inner iteration for a positive step function...
The Computational Discrete Mathematics Group uses concepts from discrete mathematics, such as combinatorics, number theory, and algebra, to develop algorithms and high performance implementations for ...
