Abstract

A result by C. C.-A. Cheng, J. H. Mckay and S. S.-S. Wang says the following: Suppose the Jacobian of AA and BB is invertible in C[x,y]\mathbb{C}[x,y] and the Jacobian of AA and ww is zero for A,B,wC[x,y]A,B,w \in \mathbb{C}[x,y]. Then wC[A]w \in \mathbb{C}[A]. We show that in CMW's result it is possible to replace C\mathbb{C} by any field of characteristic zero, and we conjecture the following 'two-dimensional Centralizer Conjecture over DD': Suppose the Jacobian of AA and BB is invertible in D[x,y]D[x,y] and the Jacobian of AA and ww is zero for A,B,wD[x,y]A,B,w \in D[x,y], DD is an integral domain of characteristic zero. Then wD[A]w \in D[A]. We show that if the famous two-dimensional Jacobian Conjecture is true, then the two-dimensional Centralizer Conjecture is true.
