R[x,y]的坐标:构造和分类

Coordinates of R[x,y]: Constructions and classifications

Eric Edo

摘要:

R是PID。本文构造并分类了R[x,y]中p_2y+Q_2(p_1x+Q_1(y))形式的所有坐标,其中p_1和p_2在qt(R)中,Q_1和Q_2在qt(R)[y]中。由这个构造(R=K[z]),我们得到了K[x,y,z](其中K是特征为0的域)的非驯服自同构s,使得s和仿射自同构生成的子群包含所有驯服自同构。

英文摘要:

Let R be a PID. We construct and classify all coordinates of R[x,y] of the form p_2y+Q_2(p_1x+Q_1(y)) with p_1 and p_2 in qt(R) and Q_1 and Q_2 in qt(R)[y]. From this construction (with R=K[z]) we obtain non tame automorphisms s of K[x,y,z] (where K is a field of characteristic 0) such that the sub-group generated by s and the affine automorphisms contains all tame automorphisms.
