The Swampland program aims to distinguish effective theories which can be completed into
quantum gravity in the ultraviolet from those which cannot. This article forms an introduction …

We review in detail a number of approaches that have been adopted to try and explain the
remarkable observation of our accelerating universe. In particular we discuss the arguments …

We outline the construction of metastable de Sitter vacua of type IIB string theory. Our
starting point is highly warped IIB compactifications with nontrivial NS and RR three-form …

The past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

We present a brief overview of attempts to construct de Sitter vacua in string theory and
explain how the results of this 20-year endeavor could point to the fact that string theory …

These lecture notes provide a pedagogical introduction, with exercises, to the techniques
used in attempts to construct vacua with stabilized moduli in string theory. The reader is only …

We investigate the embedding of brane inflation into stable compactifications of string
theory. At first sight a warped compactification geometry seems to produce a naturally flat …

Recent work is reviewed in which compactifications of string and M theory are constructed in
which all scalar fields (moduli) are massive, and supersymmetry is broken with a small …

We present a pedagogical overview of flux compactifications in string theory, from the basic
ideas to the most recent developments. We concentrate on closed-string fluxes in type-II …

A bstract We study the Symmetry Topological Field Theory in holography associated with 4d
𝒩= 1 Super Yang-Mills theory with gauge algebra 𝔰𝔲 (M). From this, all the bulk symmetry …
