DECIDING IF A POLYNOMIAL ENDOMORPHISM OVERAN AFFINE ALGEBRAIC SET IS INVERTIBLE VIA WU-RITT METHOD
基于吴方法判断代数集上多项式自同态是否为同构

We give a Grobner basis criterion for deciding if a polynomial endomorphismover an affine algebraic set is invertible. This criterion can be computed by using the Wu-Rittalgorithm. Some concrete examples are given.
