(I would like to thank one of my former students, Fina, with whom I have the pleasure of keeping in touch, because she is the one who has inspired me to open this section and her contributions have been absolutely invaluable. I am also grateful to all my students, who, one way or another, have contributed to his site. Special contributions: Fina, Joan)
