@Andreas: I did not expect to have one good answer to my question but a sort of collective answer where every one could bring one original information as indeed Amit Haim and Stefan did. It was my first question I'm sorry if is not in the spirit of mathoverflow next time I will ask thing more precisely. If I should be more precise now I would say that initial motivation was the most important part of the question for me so that Stefan answer me.
