Foreword to the Proceedings of the VIII International
Symposium on Quantum Theory and Symmetries
El Colegio Nacional, Mexico City, 5–9 August 2013
The Quantum Theory and Symmetries (QTS) international symposia are periodic biannual meetings of
the mathematical physics community with special interest in the methods of group theory in their many
incarnations, particularly in the symmetries that arise in quantum systems. The QTSs alternate with the
International Colloquia on Group Theoretical Methods in Physics since 1999, when Professor HeinzDietrich Doebner organized the first one in Goslar, Germany. Subsequent symposia were held in Kraków,
Poland (2001), Cincinnati, USA (2003), Varna, Bulgaria (2005), Valladolid, Spain (2007), Lexington,
USA (2009), and Praha, Czech Republic (2011); the eighth QTS was awarded to Mexico (2013), and the
next one (2015) will take place in Yerevan, Armenia.
The members of the International Conference Board of the QTS Symposia are:
Laurence Boyle
Vladimir Dobrev
Vladimir Man’ko

Periodic meetings of researchers in the widening domains of symmetry methods help to keep their
various mathematical dialects and physical application fields in contact and synergy. The scientific
community also appreciates venues that provide a window to the cultures of the world. It is indeed a
privilege that few professions have. For those of us aware of the course of 21st century civilization, this
is a source of worldly knowledge and inspiration. While many previous meetings in Mexico have taken
place in attractive tourist locations, we decided to accept the invitation of El Colegio Nacional to hold
QTS8 in the heart of the Mexico City megalopolis, sheltered in their excellently refurbished late-17th
century installations originally built as a convent and novitiate. Walking to and from the daily sessions,
the participants were immersed in the restless multitude of visitors, merchants and shoppers that pursue
their trades in the central quarter of ancient Tenochtitlan, which for most of its history has been the
largest conurbation of America. An evening at the Palacio de Bellas Artes for a performance of the Ballet
Folklórico left a lasting impression on our history and art.

Both the VIII International Symposium on Quantum Theory and Symmetries, and the previous two
weeks of the XLIII Latin American School of Physics, were hosted as part of the activities of El Colegio
Nacional in 2013, coordinated by Member Professor Octavio Novaro Peñalosa. This institution provided

the conference halls of its venue in Mexico City, as well as the support staff for projection facilities, coffee
breaks and lunches during the week. Support for administration was provided by the Sociedad Mexicana
de Física AC and by the Instituto de Ciencias Físicas, UNAM. The Symposium gathered 98 participants,
including 50 researchers, 9 postdoctoral associates, 23 graduate students and 16 student auditors. There
were 10 plenary presentations, 50 contributed talks and 20 posters. The symposium was well attended
by Mexican participants, several of them students who were also present in the Latin American School
of Physics.
