Riccardo D'Auria

Riccardo D'Auria (born 1940) is an Italian theoretical physicist and an emeritus full professor of the Polytechnic University of Turin.

Early life and education

Riccardo D'Auria was born in Rome, Italy in 1940. He graduated in Physics at the University of Turin, under the supervision of Prof. Tullio Regge.

Career

He was an associate professor at the University of Turin, a full professor at University of Padua and, eventually, at the Polytechnic University of Turin. There he founded a theoretical physics group, oriented towards particle physics, field theory, gravity and supergravity. From 1996 to 2000 he was director of the Department of Physics of the Polytechnic University of Turin.

He spent several extended periods at CERN and at the University of California, Los Angeles.

Contributions

Riccardo D'Auria contributed, in the early years of superstring theory and in collaboration with a group of string theorists, to the introduction of internal flavour symmetry and color symmetry in a string algebra.

In collaboration with Pietro G. Frè (and following a proposal by Y. Ne'eman and T. Regge), he developed a new approach to supergravity called '. Of special interest is the application of this approach to the study of theories where the physical fields include p-forms of degree higher than one, in particular, the eleven-dimensional supergravity, the low-energy description of M-theory.  By a generalisation of the Cartan-Maurer equations of an ordinary (graded) Lie algebra, a new graded algebra was introduced, called , by means of which a geometric approach to higher-dimensional theories can be realised This mathematical structure is the first example of an L-infinity algebra developed in mathematics some ten years after their original results, and formulated in the space dual to the space of differential p-forms.
