Euler Sequence and Koszul complex of a module
Bjorn Andreas, Darío Sánchez Gómez, Fernando Sancho de Salas
We construct relative and global Euler sequences of a module. We apply it to prove some acyclicity results of the Koszul complex of a module and to compute the cohomology of the sh…
SU(5) Heterotic Standard Model Bundles
Bjorn Andreas, Norbert Hoffmann
We construct a class of stable SU(5) bundles on an elliptically fibered Calabi-Yau threefold with two sections, a variant of the ordinary Weierstrass fibration, which admits a free…
New Examples of Stable Bundles on Calabi-Yau Threefolds
Bjorn Andreas, Norbert Hoffmann
In this paper we present a construction of stable bundles on Calabi-Yau threefolds using the method of bundle extensions. This construction applies to any given Calabi-Yau threefol…
On the Existence of Stable bundles with prescribed Chern classes on Calabi-Yau threefolds
Bjorn Andreas, Gottfried Curio
We prove a case of the conjecture of Douglas, Reinbacher and Yau about the existence of stable vector bundles with prescribed Chern classes on a Calabi-Yau threefold. For this purp…
Spectral Bundles and the DRY-Conjecture
Bjorn Andreas, Gottfried Curio
Supersymmetric heterotic string models, built from a Calabi-Yau threefold endowed with a stable vector bundle , usually start from a phenomenologically motivated choice of a…
Heterotic Non-Kahler Geometries via Polystable Bundles on Calabi-Yau Threefolds
Bjorn Andreas, Mario Garcia-Fernandez
In arXiv:1008.1018 it is shown that a given stable vector bundle on a Calabi-Yau threefold which satisfies can be deformed to a solution of the Strominger s…
