This chapter collects hints to solve various exercises. These solutions are not complete by any means, the given arguments can only be considered at best to be heuristic and need to be completed by the reader. These are a level above the hints given in each corresponding exercise which are given because we believe that some of the exercises may be difficult or even that some misunderstanding may occur.
