F-theory with quantized fluxes [PDF]
Advances in Theoretical and Mathematical Physics, 1999 We present evidence that the CHL string in eight dimensions is dual to F-theory compactified on an elliptic K3 with a $ _{0}(2)$ monodromy group. The monodromy group $ _{0}(2)$ allows one to turn on the flux of an antisymmetric two form along the base.

G 4 flux, algebraic cycles and complex structure moduli stabilization
Journal of High Energy Physics, 2021 We construct G 4 fluxes that stabilize all of the 426 complex structure moduli of the sextic Calabi-Yau fourfold at the Fermat point. Studying flux stabilization usually requires solving Picard-Fuchs equations, which becomes unfeasible for models with ...

Stringy Cosmic Strings and Compactifications of F-theory [PDF]
Nucl.Phys. B503 (1997) 177-192, 1997 We construct stringy cosmic string solutions corresponding to compactifications of F-theory on several elliptic Calabi-Yau manifolds by solving the equations of motion of low energy effective action of ten dimensional type IIB superstring theory. Existence of such solutions supports the compactifications of F-theory.

A note on orientifolds and F-theory [PDF]
Physics Letters B, 1997 An orientifold of Type-IIB theory on a $K3$ realized as a $Z_2$ orbifold is constructed which corresponds to F-theory compactification on a Calabi-Yau orbifold with Hodge numbers $(51, 3)$. The T-dual of this model is analogous to an orbifold with discrete torsion in that the action of orientation reversal has an additional phase on the twisted sectors,

Journal of High Energy Physics, 2022 D3 branes in the vicinity of an E6, E7, or E8 stack of 7-branes in flat space are known to host at low energy a famous class of strongly-coupled N $$ \mathcal{N} $$ = 2 superconformal field theories featuring exceptional global symmetry. What if, instead,

F-Theory on Calabi-Yau Fourfolds [PDF]
Phys.Lett. B387 (1996) 750-758, 1996 We discuss some aspects of F-theory in four dimensions on elliptically fibered Calabi-Yau fourfolds which are Calabi-Yau threefold fibrations. A particularly simple class of such manifolds emerges for fourfolds in which the generic Calabi-Yau threefold fiber is itself an elliptic fibration and is K3 fibered.

PARALLELED CHARACTERS IN THE DRAMATIC WORKS OF HORTENSIA PAPADAT-BENGESCU [PDF]
Diversitate si Identitate Culturala in Europa, 2015 This article proposes a psychoanalytical approach to two paralleled literary characters whom Hortensia Papadat-Bengescu places into opposition in order to introduce her readers to feminine hypostases of wish fulfilment.

F Theory on K3xK3 and Instantons on 7-branes [PDF]
Nucl.Phys. B510 (1998) 232-246, 1997 We discuss N=2 supersymmetric compactifications to four dimensions from the point of view of F-theory and heterotic theory. In a relatively simple setup, we illustrate the spectral theory for vector bundles on K3xT^2 and discuss the heterotic -- F-theory map. The moduli space of instantons on the 7-brane wrapped around K3 is discussed from the point of
