The present collection contains 21 papers by participants of the
O'Raifeartaigh Symposium on Non-Perturbative and Symmetry Methods
in Field Theory,
held at Budapest, June 22−24, 2006. The symposium served
as a venue for an exchange of ideas on recent developments
in field theory and related subjects, and it also enhanced
the 'coherence' of a 'virtual community' of
researchers who had direct or indirect contact with
Lochlainn O'Raifeartaigh during their careers.
Indeed, about half of the 50 registered participants
were drawn from collaborators, among them several former postdoctoral
scholars at the Dublin Institute for Advanced Studies, and close colleagues of
Professor O'Raifeartaigh.
Together with the presence of two of his sons,
Conor and Cormac, this contributed especially to
a general warm feeling that dominated the meeting (the effective action of the
hot and humid weather on the participants was obviously negligible in comparison).
Being ourselves former postdocs of Lochlainn, we wish to believe that he would have liked the meeting. The appreciation of his eminent scientific contributions, and the lasting imprints made by his outstandingly human, warm personality were apparent throughout the conference. As was made explicit in several talks, many of us still miss him very much.
This is not the place to survey the work of Lochlainn O'Raifeartaigh (1933−2000), a brief account can be found at the web page maintained at Dublin Institute for Advanced Studies http://www.stp.dias.ie/Lochlainn/lochlainn.html. The best way to remember a scientist is to study his work. Having this in mind, the list of publications of Lochlainn O'Raifeartaigh is included here as a complement.
The slides of most of the 27 talks that were delivered in Budapest (out of which 15 served as the basis of reports published in this collection), and further auxiliary material can be viewed at the web page of the conference http://www.kfki.hu/~lor2006, which will be kept available for the coming years.
