A high‐order finite difference discretization strategy based on extrapolation for convection diffusion equations

- Hai-wei Sun, J. Zhang
- Mathematics
- 2004

We propose a new high-order finite difference discretization strategy, which is based on the Richardson extrapolation technique and an operator interpolation scheme, to solve convection diffusion… Expand

Pseudo almost automorphic solutions to semilinear differential equations in Banach spaces

Abstract
In this paper, we prove that the space
$(\mathit{PAA}(\mathbb{R},\mathbb{X}),\|\cdot\|_{0})$
is complete. This not only gives an affirmative answer to a basic problem in this field, but… Expand

The Mean Field Theory In EM Procedures For Markov Random Fields

- J. Zhang
- MathematicsProceedings of the Seventh Workshop on…
- 23 September 1991

The EM (expectation-maximization) algorithm is a maxinium-likelihood parameter estimation procedure for incomplete data problems in which part of the data is hidden, or unobservable. In many signal… Expand

Composition of pseudo almost automorphic and asymptotically almost automorphic functions

This paper is concerned with pseudo almost automorphic functions, which are more general and complicated than pseudo almost periodic functions and asymptotically almost automorphic functions. New… Expand

Sculpting of an erodible body by flowing water

Accelerated multigrid high accuracy solution of the convection-diffusion equation with high Reynolds number

- J. Zhang
- Mathematics
- 1997

A fourth-order compact finite difference scheme is employed with the multigrid algorithm to obtain highly accurate numerical solution of the convection-diffusion equation with very high Reynolds… Expand

Persistent homology and Floer-Novikov theory

- Michael Usher, J. Zhang
- Mathematics
- 27 February 2015

We construct "barcodes" for the chain complexes over Novikov rings that arise in Novikov's Morse theory for closed one-forms and in Floer theory on not-necessarily-monotone symplectic manifolds. In… Expand

The kinematics of an untwisting solar jet in a polar coronal hole observed by SDO/AIA

- Huadong Chen, J. Zhang, Suli Ma
- Physics
- 20 January 2012

Using the multi-wavelength data from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) spacecraft, we study a jet occurring in a coronal hole near the northern pole… Expand
