Regularization of Rational Group Actions - part 2

The aim is to give a modern proof of the famous Theorem of A. Weil showing that for every rational action of an algebraic group G on a variety X there is a regular action of G on a variety Y and a G-equivariant birational map X → Y. As a guideline we use an approach given by D. Zaitsev (J. Lie Theory 5, 1995).
