A GENERAL TWO-LEVEL SUBSPACE METHOD FOR NONLINEAR OPTIMIZATION
《Journal of Computational Mathematics》2018年第6期881-902,共22页Cheng Chen Zaiwen Wen Yaxiang Yuan 
A new two-level subspace method is proposed for solving the general unconstrained minimization formulations discretized from infinite-dimensional optimization problems. At each iteration, the algorithm executes either...

FULL DISCRETE TWO-LEVEL CORRECTION SCHEME FOR NAVIER-STOKES EQUATIONS被引量：1
《Journal of Computational Mathematics》2008年第2期209-226,共18页Yanren Hou Liquan Mei 
subsidized by the State Basic Research Project (Grant No.2005CB32703);NSF of China (Grant No.10471110) and NCET
In this paper, a full discrete two-level scheme for the unsteady Navier-Stokes equations based on a time dependent projection approach is proposed. In the sense of the new projection and its related space splitting, n...

A TWO-LEVEL FINITE ELEMENT GALERKIN METHOD FOR THE NONSTATIONARY NAVIER-STOKES EQUATIONS II： TIME DISCRETIZATION被引量：6
《Journal of Computational Mathematics》2004年第1期33-54,共22页Yin-nianHe Huan-lingMiao Chun-fengRen 
In this article we consider the fully discrete two-level finite element Galerkin method for the two-dimensional nonstationary incompressible Navier-Stokes equations. This method consists in dealing with the fully disc...
A TWO-LEVEL FINITE ELEMENT GALERKIN METHOD FOR THE NONSTATIONARY NAVIER-STOKES EQUATIONS I： SPATIAL DISCRETIZATION被引量：4
《Journal of Computational Mathematics》2004年第1期21-32,共12页Yin-nianHe 
In this article we consider a two-level finite element Galerkin method using mixed finite elements for the two-dimensional nonstationary incompressible Navier-Stokes equations. The method yields a H^1-optimal velocity...
