Miguel Angel Virasoro
Encyclopedia
Miguel Angel Virasoro is an Argentine physicist who did most of his work in Italy
. The Virasoro algebra
is named after him. Together with Giorgio Parisi
and Marc Mezard he discovered the
Ultrametric organization of low temperature spin glass states in infinite dimensions.
He was a director of the International Centre for Theoretical Physics
(ICTP) from 1995 to 2002.
He taught physical-mathematical models for economy at Università di Roma "La Sapienza". He now teaches electromagnetism
for physics still at "La Sapienza".
