F-theory is perhaps the most general currently available approach to study non-perturbative
string compactifications in their geometric, large radius regime. It opens up a wide and ever …

A bstract F-theory on singular elliptically fibered Calabi-Yau four-folds provides a setting to
geometrically study four-dimensional\(\mathcal {N}= 1\) supersymmetric gauge theories …

A bstract We interpret infinite-distance limits in the complex structure moduli space of F-
theory compactifications to six dimensions in the light of general ideas in quantum gravity …

A bstract We study the non-perturbative superpotential generated by D (-1)-branes in type
IIB compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. To compute the …

We present a simple algebraic construction of all the small resolutions for the SU (5)
Weierstrass model. Each resolution corresponds to a subchamber on the Coulomb branch …

A bstract We study elliptic fibrations that geometrically engineer an SU (2)× G 2 gauge
theory realized by a Weierstrass model for the collision III+ I* ns 0. We find all the distinct …

We study the geometry of elliptic fibrations satisfying the conditions of Step 8 of Tate's
algorithm. We call such geometries F $ _4 $-models, as the dual graph of their special fiber …

We explore how introducing a non-trivial Mordell-Weil group changes the structure of the
Coulomb phases of a five-dimensional gauge theory from an M-theory compactified on an …

Abstract We perform a Kaluza–Klein reduction of eleven-dimensional supergravity on a
Calabi–Yau fourfold including terms quartic and cubic in the Riemann curvature and …
