【 摘 要 】

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 rho-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.
