Sergio Doplicher


Sergio Doplicher is an Italian mathematical physicist.
He received his doctorate under the supervision of Giovanni Jona-Lasinio. From 1976 to 2011 Doplicher was professor ordinarius of quantum mechanics in the mathematics department of the Sapienza University of Rome, retiring there in 2011 as professor emeritus. He is known for his research based on the Haag–Kastler axioms and collaborated with Rudolf Haag. Doplicher also coauthored a number of papers with John Elias Roberts, who worked for a long time in Rome. With Roberts and Haag he examined superselection rules in the algebraic quantum field theory. Doplicher and Roberts proved a reconstruction theorem for the quantum fields and gauge groups from the algebra of the observables. Later in his career, Doplicher dealt with mathematical fundamentals of quantum gravity.
Doplicher was an Invited Speaker at the International Congress of Mathematicians in Kyoto in 1990. He was awarded in 2004 the Humboldt Prize and in 2011 the Premio Nazionale del Presidente della Repubblica of the Accademia Nazionale dei Lincei. In 2012 he was elected a Fellow of the American Mathematical Society. His doctoral students include Roberto Longo.
