On the Uniqueness of the Fock Quantization of the Dirac Field in the Closed FRW Cosmology
Jerónimo Cortez, Ilda Inácio Rodrigues, Mercedes Martín-Benito +1
The Fock quantization of free fields propagating in cosmological backgrounds is in general not unambiguously defined due to the non-stationarity of the spacetime. For the case of a…

The Dimensions of the Symmetry Types of Polyhedra with Reflection Groups
M. Rostami, Henrique F. da Cruz, Ilda I. Rodrigues
Let P and Q be convex polyhedra in E3 with face lattices F(P) and F(Q) and symmetry groups G(P) and G(Q), respectively. Then, P and Q are called face equivalent if there is a latti…
