Evolutionary p(x)-Laplacian Equation with a Convection Term
《Acta Mathematicae Applicatae Sinica》2019年第3期655-670,共16页Hua-shui ZHAN 
Supported by the National Natural Science Foundation of China(No.2015J01592,No.2019J01858)
The paper studies an evolutionary p(x)-Laplacian equation with a convection term ut=div(ρα|■u|p(x)-2■u)+∑N i=1■bi(u)/■xi,whereρ(x)=dist(x,■Ω),ess inf p(x)=p^->2.To assure the well-posedness of the solutions,...

A ROBUST SUPERLINEARLY CONVERGENT ALGORITHM FOR LINEARLY CONSTRAINED OPTIMIZATION PROBLEMS UNDER DEGENERACY
《Acta Mathematicae Applicatae Sinica》1998年第4期363-373,共11页曾庆光 贺国平 吴方 
In this paper, the problem of minimizing a convex function subject to general linear constraints is considered. An algorithm which is an extension of the method described in [4] is presented. And a new dual simplex pr...

A GENERAL TECHNIQUE FOR DEALING WITH DEGENERACY IN REDUCED GRADIENT METHODS FOR LINEARLY CONSTRAINED NONLINEAR PROGRAMMING
《Acta Mathematicae Applicatae Sinica》1994年第1期90-101,共12页韩继业 胡晓东 
In this paper we discuss the degeneracy in nonlinear programming with linear constraints, and give a technique for dealing with degeneracy in a general model of reduced gradient algorithms. Under the assumption that t...
