Abstract
If R is an integral domain and K is its field of fractions, we let Int (R) stand for the subring of K [x] which maps R into itself. We show that if R is the ring of integers of a p-adic field, then Int (R) is generated, as an R-algebra, by the coefficients of the endomorphisms of any Lubin-Tate group attached to R.
