Weakly coupled de Sitter in massive IIA compactifications Dibitetto, Giuseppe
Description
I will briefly review the issues of de Sitter vacua in string theory in relation to the various swampland conjectures which suggest a tension
between an effective description of universe in accelerated expansion and its possible unitary UV completion.
Subsequently I will address this UV/IR puzzle within the specific context of massive type IIA compactifications and discuss the status of the
search for classical de Sitter solutions arising from reductions on SU(3) structure manifolds. I will then conclude by discussing the
controversial issue of defining a good weakly coupled regime for such backgrounds.
