Cosmology

Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.

In this talk, we show how the swampland conjecture, which has
recently been attracting attention in string theory and gravity
theory, relates to the slow-roll condition of inflation. First, we
will briefly explain the reason why we focus on the swampland
conjecture to investigate the dynamics of inflation. Next, we discuss
