Extended Theories of Gravitation

The MS2Discovery Interdisciplinary Research Institute Seminar


Lorenzo Fatibene, University of Turin, Italy

Since 2011 Lorenzo Fatibene is a full professor of Mathematical Physics at the Department of Mathematics “Giuseppe Peano” of the University of Torino (Italy). He has a degree in Physics (1992) and a PhD in Mathematics (1999) and he has been a researcher at the University of Torino between 1999 and 2011. His research interests are in geometrical methods for field theory, variational calculus and conservation laws in generally covariant and gauge theories. Recently, he is investigating extended theories of gravitation and their applications to astrophysical and cosmological models.


Extended Theories of Gravitation


We shall introduce Extended Theories of Gravitation which extend standard General Relativity by allowing geometries on spacetime more general than the usual Lorentzian metric structure. Palatini f(R)-theories are considered as an example and application. Their ability to model dark matter and dark energy as the effect of modified dynamics of gravitational field rather than fundamental matter fields and applications to cosmology will be discussed.
