A theoretical description of cosmological inflation,
dark energy (cosmological constant) and dark
matter in supergravity is non-trivial. I review the
standard procedures and propose the new ones
based on recent developments in supergravity theory.
Phenomenological aspects of dark matter in high-scale SUSY
breaking scenario are also briefly discussed.
P.S. Based on recent publications of myself with collaborators,
P.P.S. My talk may be also suitable for Field Theory & String Theory
