Abstract
We consider polynomials and rational functions which are invariant under the action of a finite linear group. The aim is to give a survey over the knowledge on some structural properties of such rings and fields of invariants. Particular emphasis lies on the modular case, where the characteristic of the ground field divides the group order.
