Nuclear Physics B, 1996 We construct compact examples of D-manifolds for type IIB strings. The construction has a natural interpretation in terms of compactification of a 12-dimensional `F-theory'. We provide evidence for a more natural reformulation of type IIB theory in terms

F‐theory and Dark Energy [PDF]
Fortschritte der Physik, 2018 Motivated by its potential use as a starting point for solving various cosmological constant problems, we study F‐theory compactified on the warped product Rtime×S3×Y8 where Y8 is a Spin(7) manifold, and the S3 factor is the target space of an SU(2) Wess–

F-theory and Orientifolds [PDF]
Nuclear Physics B, 1996 By analyzing $F$-theory on $K3$ near the orbifold limit of $K3$ we establish the equivalence between $F$-theory on $K3$ and an orientifold of type IIB on $T^2$, which in turn, is related by a T-duality transformation to type I theory on $T^2$.

Modern Physics Letters A, 2005 After a brief review of string and $M$-Theory we point out some deficiencies. Partly to cure them, we present several arguments for ``$F$-Theory'', enlarging spacetime to $(2, 10)$ signature, following the original suggestion of C. Vafa.

F-theory with worldvolume sectioning [PDF]
Journal of High Energy Physics, 2021 We describe the worldvolume for the bosonic sector of the lower-dimensional F-theory that embeds 5D, N=1 M-theory and the 4D type II superstring. This theory is a complexification of the fundamental 5-brane theory that embeds the 4D, N=1 M-theory of the ...

New Fourfolds from F-Theory [PDF]
, 2015 In this paper, we apply Borcea-Voisin's construction and give new examples of fourfolds containing a del Pezzo surface of degree six, which admit an elliptic fibration on a smooth threefold.

Nuclear Physics B, 1997 We consider BPS configurations in theories with two timelike directions from the perspective of the supersymmetry algebra. We show that whereas a BPS state in a theory with one timelike variable must have positive energy, in a theory with two times any ...

Physics Letters B, 2014 We study the dynamics of axion-like fields in F-theory and suggest that they can serve as inflatons in models of natural inflation. The axions arise from harmonic three-forms on the F-theory compactification space and parameterize a complex torus that ...

Towards bootstrapping F-theory
Journal of High Energy PhysicsWe consider type IIB string theory with N D3 branes and various configurations of sevenbranes, such that the string coupling g s is fixed to a constant finite value.

Probing F-theory With Branes [PDF]
Physics Letters B, 1996 Last week, A. Sen found an explicit type I string compactification dual to the eight-dimensional F-theory construction with SO(8)^4 nonabelian gauge symmetry.
