Besides his veryuseful scientific advices, his consideration, patience and kindness was a greatsupport for me. His brilliant insight significantly helped me understand thesubject and go in the right direction. Although he was very busy, he spent alot of time with me, patiently read every line of my thesis and corrected it.
