We review the holographic correspondence between field theories and string/M theory,
focusing on the relation between compactifications of string/M theory on Anti-de Sitter …

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 …

A bstract As a refinement of the Swampland Distance Conjecture, we propose that a
quantum gravitational theory in an infinite distance limit of its moduli space either …

It is argued that every Calabi-Yau manifold X with a mirror Y admits a family of
supersymmetric toroidal 3-cycles. Moreover the moduli space of such cycles together with …

We study compactifications of F-theory on certain Calabi-Yau threefolds. We find that N= 2
dualities of type II/heterotic strings in 4 dimensions get promoted to N= 1 dualities between …

Using the recent advances in our understanding of non-perturbative aspects of type 11
strings we show how non-trivial exact results for N= 2 quantum field theories can be reduced …

Using “Tate's algorithm,” we identify loci in the moduli of F-theory compactifications
corresponding to enhanced gauge symmetry. We apply this to test the proposed F …

We investigate the correspondence between existence/stability of BPS states in type-II string
theory compactified on a Calabi-Yau manifold and BPS solutions of four-dimensional N= 2 …

The primary purpose of these lecture notes is to explore the moduli space of type IIA, type
IIB, and heterotic string compactified on a K3 surface. The main tool which is invoked is that …

We show how the Riemann surface σ of N= 2 Yang-Mills field theory arises in type II string
compactifications on Calabi-Yau threefolds. The relevant local geometry is given by …
