Higher-Dimensional Integrable Systems Induced by Motions of Curves in Affine Geometries被引量：2
《Chinese Physics Letters》2008年第6期1931-1934,共4页李艳艳 屈长征 
Supported by the National Natural Science Foundation of China under Grant No 10671156, and the Program for New Century Excellent Talents in University （NCET-04-0968）
We discuss the motions of curves by introducing an extra spatial variable or equivalently, moving surfaces in arffine geometries. It is shown that the 2 ＋1-dimensional breaking soliton equation and a 2 ＋ 1-dimension...

Conditional Lie Backlund Symmetries of Hamilton-Jacobi Equations被引量：1
《Chinese Physics Letters》2007年第12期3293-3296,共4页王丽真 勾明 屈长征 
Supported by the National Natural Science Foundation of China under Grant No 10671156, and the Programme for New Century Excellent Talents in University （NCET-04-0968）.
The conditional Lie Bgcklund symmetry method, as a generalization of the conditional symmetry and Lie Bgcklund symmetry methods, is developed to study the Hamilton-Jacobi equations. It is shown that the equation ut = ...
Linearization of Systems of Nonlinear Diffusion Equations
《Chinese Physics Letters》2007年第9期2467-2470,共4页康静 屈长征 
Supported by the National Natural Science Foundation of China under Grant No 10671156, and the Programme for New Century Excellent Talents in University （NCET-04-0968）.
We investigate the linearization of systems of n-component nonlinear diffusion equations; such systems have physical applications in soil science, mathematical biology and invariant curve flows. Equivalence transforma...
