Inflation as a spontaneous symmetry breaking of Weyl symmetry
A. Barnaveli, S. Lucat, T. Prokopec
In this paper we study a novel realization of inflation, based on Weyl invariant gravity with torsion. We show that requiring the classical action for the scalar field to be Weyl i…

Conformal symmetry and the cosmological constant problem
Stefano Lucat, Tomislav Prokopec, Bogumila Swiezewska
We argue that, when a theory of gravity and matter is endowed with (classical) conformal symmetry, the fine tuning required to obtain the cosmological constant at its observed valu…
