Abstract [en]

We develop techniques to split explicitly the sheaf of principal parts P-k(O(n)) as left and right module on the projective line over an arbitrary ring. We then apply the techniques developed to split the principal parts P-k(O(n)) for all n is an element of Z and k >= 1 as left and right O-module on the projective line over any field of characteristic zero giving a complete description of the principal parts on the projective line.
