Let K be any field and G be a finite group. Noether's problem asks whether the fixed field is rational (=purely transcendental) over K. We will prove that if G is a non-abelian p-g…

Let K be an arbitrary field. We will determine explicitly all the nontrivial finite groups of essential dimension one over K.
