Resumen de Some stably tame polynomial automorphisms

Sooraj Kuttykrishnan

• We study the structure of length three polynomial automorphisms of R[X,Y] when R is a UFD. These results are used to prove that if SLm(R[X1,X2,�,Xn])=Em(R[X1,X2,�,Xn]) for all n=0 and for all m=3 then all length three polynomial automorphisms of R[X,Y] are stably tame.
