Description
In the recent article Phys. Rev. D 100, no. 4, 043533 (2019) a compact phase space generalization of
the flat de Sitter cosmology has been proposed. The main advantages of the compactification is that
physical quantities are bounded, and the quantum theory is characterized by finite dimensional Hilbert
space. The purpose of this presentation is to discuss the extraction of semiclassical effects from this
model by way of canonical effective methods. First, a brief review of canonical effective methods is
given. Afterwards, we discuss the character of the semiclassical solutions of the compact phase space
cosmological model. Finally, a relation between the behavior of the quantum fluctuations of the
cosmological sector and the holographic Bousso bound is discussed.
