Some Polynomial Maps with jacobian Rank Two or Three
收藏 引用
Algebra Colloquium 2022年 第2期29卷 341-360页
作者: Dan Yan MOE-LCSM School of Mathematics and Statistics Hunan Normal UniversityChangsha 410081China
We classify all polynomial maps of the form H=(u(x,y,z),v(x,y,z),h(x,y))in the case when the jacobian matrix of H is nilpotent and the highest degree of z in v is no more than *** addition,we generalize the structure ... 详细信息

Algebra Colloquium 2016年 第4期23卷 663-680页
作者: Michiel de Bondt Dan Yan Department of Mathematics Radboud University Nijmegen The Netherlands Department of Mathematics and Computer ScienceHunan Normal University Changsha 410006 China
Jedrzejewicz showed that a polynomial map over a field of characteristic zero is invertible, if and only if the corresponding endomorphism maps irreducible polynomials to irreducible polynomials. Furthermore, he showe... 详细信息

Two Characterizations of Diffeomorphisms of Euclidean Space
收藏 引用
Acta Mathematica Sinica,English Series 2003年 第4期19卷 739-744页

Two characterizations for a local diffeomorphism of R^n to be global one aregiven in terms of associated Wazewski equations. The two characterizations could be useful for theinvestigation of the jacobian conjecture.

Some Coordinate Polynomials in Three Variables
收藏 引用
Chinese Quarterly Journal of Mathematics 2006年 第4期21卷 482-487页
作者: GONG Sheng-jun LI Shang-zhi Department of Mathematics University of Science and Technology of China Hefei 230026 China
In this paper, we introduce a polynomial sequence in K[x], in which two neighbor polynomials satisfy a wonderful property. Using that,we give partial answer of an open problem: ifφ(x, y, z) = (f(x, y), g(x, y... 详细信息
