Physics of F-theory compactifications without section
A bstractWe study the physics of F-theory compactifications on genus-one fibrations without section by using an M-theory dual description. The five-dimensional action obtained by considering M-theory
The N=1 effective action of F-theory compactifications
Type II string theory and modularity
This paper, in a sense, completes a series of three papers. In the previous two [1],[2], we have explored the possibility of refining the K-theory partition function in type II string theories using
A Spin(7) Conifold Transition in Type IIB as an F-theory Flop
We consider type IIB string theory compactified on an 8-dimensional Spin(7) manifold with N D5-branes, undergoing a conifold transition to a geometry with no branes and N units of dual 3-form RR flux
Mathematics Underlying the F-Theory/Heterotic String Duality in Eight Dimensions
We give an analytic description of the moduli space of classical vacua for F-theory compactified on elliptic K3 surfaces, on open tubular regions near the two Type II boundary divisors. The structure
Evidence for F(uzz) theory
We show that in the decoupling limit of an F-theory compactification, the internal directions of the seven-branes must wrap a non-commutative four-cycle $ \mathcal{S} $. We introduce a general method
Lectures on F-theory compactifications and model building
These lecture notes are devoted to formal and phenomenological aspects of F-theory. We begin with a pedagogical introduction to the general concepts of F-theory, covering classic topics such as the
Aspects of Fibers, Fibrations and their Non-Compact Limits in F-theory and Topological String Theory
This thesis presents results about F-theory and topological string theory on genus one fibered Calabi-Yau manifolds and their non-compact limits. In the first part we work in the fiber based approach


Compact Riemannian 7-manifolds with holonomy $G\sb 2$. II
This is the second of two papers about metrics of holonomy G2 on compact 7manifolds. In our first paper [15] we established the existence of a family of metrics of holonomy G2 on a single, compact,
New Connections Between String Theories
We consider the R→0 limit of toroidal compactification in various string theories. This leads to new connections between seemingly different string theories: IIA and IIB, open and closed, oriented
