The Standard Model on the Quintic
Ralph Blumenhagen, Volker Braun, Boris Kors +1
We describe the general geometrical framework of brane world constructions in orientifolds of type IIA string theory with D6-branes wrapping 3-cycles in a Calabi-Yau 3-fold, and po…

K-Theory Torsion
Volker Braun
The Chern isomorphism determines the free part of the K-groups from ordinary cohomology. Thus to really understand the implications of K-theory for physics one must look at manifol…

On extremal transitions of Calabi-Yau threefolds and the singularity of the associated 7-space from rolling
Volker Braun, Chien-Hao Liu
M-theory compactification leads one to consider 7-manifolds obtained by rolling Calabi-Yau threefolds in the web of Calabi-Yau moduli spaces. The resulting 7-space in general has s…
