The tadpole conjecture in asymptotic limits

Journal of High Energy Physics, 2022
The tadpole conjecture suggests that the complete stabilization of complex structure deformations in Type IIB and F-theory flux compactifications is severely obstructed by the tadpole bound on the fluxes.

A worldsheet description of flux compactifications

Journal of High Energy Physics
We demonstrate how recent developments in string field theory provide a framework to systematically study type II flux compactifications with non-trivial Ramond-Ramond profiles.

SO(32) heterotic standard model vacua in general Calabi-Yau compactifications

Journal of High Energy Physics, 2018
We study a direct flux breaking scenario in SO(32) heterotic string theory on general Calabi-Yau threefolds. The direct flux breaking, corresponding to hypercharge flux breaking in the F-theory context, allows us to derive the Standard Model in general ...

Fluxes, vacua, and tadpoles meet Landau-Ginzburg and Fermat

Journal of High Energy Physics, 2022
Type IIB flux vacua based on Landau-Ginzburg models without Kähler deformations provide fully-controlled insights into the non-geometric and strongly-coupled string landscape.

Fluxes, Gaugings and Gaugino Condensates [PDF]

J.Phys.Conf.Ser.53:611-620,2006, 2006
Based on the correspondence between the N = 1 superstring compactifications with fluxes and the N = 4 gauged supergravities, we study effective N = 1 four-dimensional supergravity potentials arising from fluxes and gaugino condensates in the framework of orbifold limits of (generalized) Calabi-Yau compactifications.

Late-time Cosmic Dynamics from M-theory

, 2003
We consider the behaviour of the cosmological acceleration for time-dependent hyperbolic and flux compactifications of M-theory, with an exponential potential.

Symmetric fluxes and small tadpoles

Journal of High Energy Physics, 2023
The analysis of type IIB flux vacua on warped Calabi-Yau orientifolds becomes considerably involved for a large number of complex structure fields.

D-branes on AdS flux compactifications [PDF]

, 2007
We study D-branes in N=1 flux compactifications to AdS_4. We derive their supersymmetry conditions and express them in terms of background generalized calibrations.

On the homology of big mapping class groups

Journal of Topology, Volume 17, Issue 4, December 2024.
Abstract We prove that the mapping class group of the one‐holed Cantor tree surface is acyclic. This in turn determines the homology of the mapping class group of the once‐punctured Cantor tree surface (i.e. the plane minus a Cantor set), in particular answering a recent question of Calegari and Chen.

Comments on M$_{24}$ representations and $CY_3$ geometries [PDF]

, 2014
We show using string dualities that Mathieu moonshine controls Gromov-Witten invariants and periods of the holomorphic 3-form $\Omega$ for certain $CY_3$ manifolds.
