On Periods for String Compactifications
P. Berglund, E. Derrick, T. Hübsch +1
Motivated by recent developments in the computation of periods for string compactifications with , we develop a complementary method which also produces a convenient basis for…
Mirror Symmetry for Hypersurfaces in Weighted Projective Space and Topological Couplings
P. Berglund, S. Katz
By means of toric geometry we study hypersurfaces in weighted projective space of dimension four. In particular we compute for a given manifold its intrinsic topological coupling.…
Periods for Calabi--Yau and Landau--Ginzburg Vacua
Per Berglund, Philip Candelas, Xenia de la Ossa +4
The complete structure of the moduli space of \cys\ and the associated Landau-Ginzburg theories, and hence also of the corresponding low-energy effective theory that results from (…
Dimensionally Reduced Landau-Ginzburg Orbifolds with Discrete Torsion
P. Berglund
It is observed that a large class of string vacua with superfields can be rewritten as Landau_Ginzburg orbifolds with discrete torsion and . The naive geometric…
