[phys4phys] Group for Gravitation, Particles and Fields seminar, Friday, 20 December 2024

Dear colleagues,

You are cordially invited to the seminar of the Group for Gravitation, 
Particles and Fields, which will be held on Friday, 20 December 2024, at 
11:00 at the Institute of Physics Belgrade, lecture hall 360.

The talk entitled:

Scalar field on fuzzy de Sitter space

will be given by Bojana Brkić (Faculty of Physics Belgrade).

Abstract: We study a scalar field on a noncommutative model of 
spacetime, the fuzzy de Sitter space, which is based on the algebra of 
the de Sitter group SO(1, d) and its unitary irreducible 
representations. We solve the Klein-Gordon equation in d = 2, 4 and 
show, using a specific choice of coordinates and operator ordering, that 
all commutative field modes can be promoted to solutions of the fuzzy 
Klein-Gordon equation. After that, we discuss the completeness of this 
set of modes.
