Automorphisms of simples Danielewski algebras.

Let R be a commutative integral domain with unity that contains ℚ. In this paper we describe the R-automorphism group of R-algebras of the form R[x,y,z]/(c(x)z − q(x,y)), where c(x) ∈ R[x] is quasi-monic and q(x,y) ∈ R[x,y] is quasi-monic of degree at least two with respect to y.
