| Aug 18, 2011 at 9:38 | comment | added | Martin Brandenburg | It was hard for me to understand the content your question, so let me rephrase it (perhaps also for others): Every flat module is torsionfree. Over a Prüfer domain, every torsionfree module is flat. Now in general assume that even all powers of $M$ are torsionfree and nonzero; does this suffice to conclude that $M$ is flat? If not (which I suspect), what is a counterexample? | |
