... holds in any equicharacteristic regular local ring, not necessarily of characteristic p. In general, it is false that for each ideal Z in an arbitrary ring there exists an integer I such that for all positive integers n, the integral closure of Z’+n is contained in I”. For example, if R = k[.X’, Y]/ ...
