The Sen Limit
A. Clingher, R. Donagi, M. Wijnholt
F-theory compactifications on elliptic Calabi-Yau manifolds may be related to IIb compactifications by taking a certain limit in complex structure moduli space, introduced by A. Se…

Weak Coupling, Degeneration and Log Calabi-Yau Spaces
R. Donagi, S. Katz, M. Wijnholt
We establish a new weak coupling limit in F-theory. The new limit may be thought of as the process in which a local model bubbles off from the rest of the Calabi-Yau. The construct…

On Seven-Brane Dependent Instanton Prefactors in F-theory
Mirjam Cvetič, Ron Donagi, James Halverson +1
We study the moduli-dependent prefactor of M5-instanton corrections to the superpotential in four-dimensional F-theory compactifications. In light of the M-theory and type IIb limi…
