Dualities between K3 fibered Calabi-Yau three-folds
Mitsuko Abe
We propose a way to examine N=1 and N=2 string dualities on Calabi-Yau three-folds or extensions. Our way is to find out or to construct two types of toric representations of a Cal…
Puzzles on the Duality between Heterotic and Type IIA Strings
Mitsuko Abe, Masamichi Sato
We discuss the possibility of the extension of the duality between the webs of heterotic string and the type IIA string to Calabi-Yau 3-folds with another K3 fiber by comparing the…
SO(2,1) Covariant IIB Superalgebra
Mitsuko Abe, Machiko Hatsuda, Kiyoshi Kamimura +1
We propose a type IIB super-Poincare algebra with SO(2,1) covariant central extension. Together with SO(2,1) and SO(9,1) generators, a SO(2,1) triplet (momenta), a Majorana-spinor…
Calabi-Yau manifolds constructed by Borcea-Voisin method
Mitsuko Abe, Masamichi Sato
We construct Calabi-Yau manifolds and their mirrors from K3 surfaces. This method was first developed by Borcea and Voisin. We examined their properties torically and checked mirro…
The Partition Function in the Four-Dimensional Schwarz-type Topological Half-Flat Two-Form Gravity
Mitsuko Abe
We derive the partition functions of the Schwarz-type four-dimensional topological half-flat 2-form gravity model on K3-surface or T^4 up to on-shell one-loop corrections. In this…
Moduli Spaces in the Four-Dimensional Topological Half-Flat Gravity
Mitsuko Abe
We classify the moduli spaces of the four-dimensional topological half-flat gravity models by using the canonical bundle. For a K3-surface or four-dimensional torus, they describe…
