comment Careers advice for Ph.D.s without current postdocs or university jobs
@Pete: This does not make sense; someone more experienced is not entitled to provided more accurate information than someone inexperienced but can give the right advice. I consider the fact I was an undergraduate in a liberal arts colleges to be an advantage, not the reverse. It is two years now, and I still think my advice makes a lot of sense to someone in Dr H's position.

I am really embarrassed, my memory is not accurate; the papers asked whether $\pi_{1}G$ is free instead. Sorry for raisng the wrong question at here.

You mean simple ones, or any? I did read Bott's collective papers but never seen this theorem. I shall check the link.
