Heterotic flux compactifications and their moduli
, 2006
"... We study supersymmetric compactification to four dimensions with nonzero Hflux in heterotic string theory. The background metric is generically conformally balanced and can be conformally Kähler if the primitive part of the Hflux vanishes. Analyzing the linearized variational equations, we write ..."

Preference for a Vanishingly Small Cosmological Constant in Supersymmetric Vacua in a Type IIB String Theory Model
"... We study the probability distribution P (Λ) of the cosmological constant Λ in a specific set of KKLT type models of supersymmetric IIB vacua. We show that, as we sweep through the quantized flux values in this flux compactification, P (Λ) behaves divergent at Λ = 0 − and the median magnitude of Λ d ..."

Continuous low electron flux anomaly has been observed before the occurrence of the H1N1 pandemics in Mexico
SISSA 31/2008/FMEP Comparing two different Ktheoretical classifications of Dbranes
, 805
"... We consider the two main classification schemes of compact Dbrane charges via Ktheory, in the case of vanishing Hflux: the Gysin map approach, concerning the charge related to the entire trajectory, and the AtiyahHirzebruch spectral sequence, concerning the charge conserved in time. Then, we fin ..."

RAMONDRAMOND FIELDS, FRACTIONAL BRANES AND ORBIFOLD DIFFERENTIAL KTHEORY
, 2007
"... We study Dbranes and RamondRamond fields on global orbifolds of Type II string theory with vanishing Hflux using methods of equivariant Ktheory and Khomology. We illustrate how Bredon equivariant cohomology naturally realizes stringy orbifold cohomology. We emphasize its role as the correct co ..."

"... We consider supersymmetric compactifications of type IIB and the weakly coupled heterotic string with G resp. Hflux and gaugino condensation in a hidden sector included. We point out that proper inclusion of the nonperturbative effects changes the Hodge structure of the allowed fluxes in type IIB ..."

Effective descriptions of branes on nongeometric tori
, 2007
"... We investigate the lowenergy effective description of nongeometric compactifications constructed by Tdualizing two or three of the directions of a T³ with nonvanishing Hflux. Our approach is to introduce a D3brane in these geometries and to take an appropriate decoupling limit. In the case of ..."

"... We present a new mechanism, the STrack, to stabilize the volume modulus S in heterotic Mtheory flux compactifications along with the orbifoldsize T besides complex structure and vector bundle moduli stabilization. The key dynamical ingredient which makes the volume modulus stabilization possible, ..."

ZERO DIFFUSIONDISPERSIONSMOOTHING LIMITS FOR SCALAR CONSERVATION LAW WITH DISCONTINUOUS FLUX FUNCTION
"... Abstract. We consider multidimensional conservation laws with discontinuous flux, which are regularized with vanishing diffusion and dispersion terms and with smoothing of the flux discontinuities. We use the approach of Hmeasures [17] to investigate the zero diffusiondispersionsmoothing limit. ..."
