Abstract
{If A is a subring of a commutative ring B and if n
is a positive integer, a number of sufficient conditions are given for
``A[[X]]is nroot closed in B[[X]]'' to be equivalent to ``A is nroot
closed in B.'' In addition, it is shown that if S is a multiplicative
submonoid of the positive integers ${\bbd P}$ which is generated by
primes, then there exists a onedimensional quasilocal integral domain
A (resp., a von Neumann regular ring A) such that $S = \{ n \in {\bbd P}\mid
A$ is $n$root closed$\}$ (resp., $S = \{n \in {\bbd P}\mid A[[X]]$
is $n$rootclosed$\}$).
