Stable Sheaves Over K3 Fibrations
Bjorn Andreas, Daniel Hernandez Ruiperez, Dario Sanchez Gomez
We construct stable sheaves over K3 fibrations using a relative Fourier-Mukai transform which describes the sheaves in terms of spectral data similar to the construction for ellipt…
Deformations of Bundles and the Standard Model
Bjorn Andreas, Gottfried Curio
We modify a recently proposed heterotic model hep-th/0703210, giving three net-generations of standard model fermions, to get rid of an additional U(1) factor in the gauge group. T…
Extension Bundles and the Standard Model
Bjorn Andreas, Gottfried Curio
We construct a new class of stable vector bundles suitable for heterotic string compactifications. Using these we describe a novel way to derive the fermionic matter content of the…
Fourier-Mukai Transform and Mirror Symmetry for D-Branes on Elliptic Calabi-Yau
Bjorn Andreas, Gottfried Curio, Daniel Hernandez Ruiperez +1
Fibrewise T-duality (Fourier-Mukai transform) for D-branes on an elliptic Calabi-Yau three-fold is seen to have an expected adiabatic form for its induced cohomology operation…
On discrete Twist and Four-Flux in N=1 heterotic/F-theory compactifications
Bjorn Andreas, Gottfried Curio
We give an indirect argument for the matching of four-flux and discrete twist in the duality between N=1 heterotic string and -theory. This treats in detail the E…
