Then there exists a positive integer c such that for all integers n, the integral closure of (I + m^n) is contained in m^(n/c) + the integral closure of I. In the proof, a version of the linear Artin approximation theorem is proved.Theorem 2.7 in the published version is wrong (we thank Ray Heitmann for pointing it out). This is a corrected version (the main results still hold)Commutative Algebra13B22; 13B40; 13J10; 14B12Integral closure of ideals in excellent local ringstext
