Numbers [71] and higher were written while a lecturer, a reader and then a professor at the School of Mathematics of the University of Edinburgh.

The effect of the onset of full-time teaching, without the concomitant improvement in time-management skills, can be clearly felt in the relatively few papers I wrote during the three academic years 1998-2001. I then went on a much needed sabbatical!

Paper [82] was featured in March 2004 as an ESI hot new paper; although by that time it had cooled down considerably.

Papers [77], [83-4] and [91], and to a certain extent [92], form part of a research programme that Joan Simón and I started in 2001. That collaboration has spanned what has been a very difficult time for me personally, and if we have achieved what we set out to do, it is due in no small part to Joan's patience at a time of his professional life when, as a postdoc, production was paramount.
(Moltes gràcies, Joan!)
