Remarks on a normal subgroup of GA_n
Jakub Zygadło
We show that the subgroup generated by locally finite polynomial automorphisms of k^n is normal in GA_n. Also, some properties of normal subgroups of GA_n containing all diagonal a…

Minimal polynomial of an exponential automorphism of C^n
Jakub Zygadło
We show that the minimal polynomial of a polynomial exponential automorphism F of C^n (i.e. F=exp(D), where D is a locally nilpotent derivation) is of the form μ_F(T)=(T-1)^d, d=mi…
