On Periods for String Compactifications
P. Berglund, E. Derrick, T. Hübsch, D. Jancic
Abstract
Motivated by recent developments in the computation of periods for string compactifications with c=9, we develop a complementary method which also produces a convenient basis for related calculations. The models are realized as Calabi--Yau hypersurfaces in weighted projective spaces of dimension four or as Landau-Ginzburg vacua. The calculation reproduces known results and also allows a treatment of Landau--Ginzburg orbifolds with more than five fields.
