Riccardo D'Auria (born 1940) is an Italian theoretical physicist and an emeritus full professor of the Polytechnic University of Turin.[1]
Early life and education
[edit]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.[2]
Career
[edit]He was an associate professor at the University of Turin, a full professor at University of Padua[3] and, eventually, at the Polytechnic University of Turin. There he founded a theoretical physics group, oriented towards particle physics, field theory, gravity and supergravity.[4] From 1996 to 2000 he was director of the Department of Physics of the Polytechnic University of Turin.[1]
He spent several extended periods at CERN[5] and at the UCLA University (USA).[6]
Contributions
[edit]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.[7]
In collaboration with Pietro G. Frè (and following a proposal by Y. Ne'eman and T. Regge[8]), he developed a new approach to supergravity called geometric or rheonomic approach. 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 Cartan integrable system, by means of which a geometric approach to higher-dimensional theories can be realised[9] 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.
In collaboration with Tullio Regge, R. D'Auria explicitly constructed an asymptotically flat gravitational instanton solution[10] of the four-dimensional Einstein theory.
He also completed, with Leonardo Castellani and Sergio Ferrara, the full formulation of Special Kaehler Geometry, which allows the precise formulation of N=2 supergravity in four dimensions.[11] This eventually led him, within a different collaboration, to obtain the result of constructing the most general matter-coupled N=2 supergravity in four dimensions.[12]
