A14 (1999) 1177-1204 | | Subject: | hep-th | | Affiliation: | Hokkaido Univ. | | Abstract: | We construct a bi-linear form on the periods of Calabi-Yau spaces. These are used to obtain the prepotentials around conifold singularities in type-II strings compactified on Calabi-Yau space. The explicit construction of the bi-linear forms is achieved for the one-moduli models as well as two moduli models with K3-fibrations where the enhanced gauge symmetry is known to be observed at conifold locus. We also show how these bi-linear forms are related with the existence of flat coordinates. We list the resulting prepotentials in two moduli models around the conifold locus, which contains alpha’ corrections of 4-D N=2 SUSY SU(2) Yang-Mills theory as the stringy effect. | | Source: | arXiv, hep-th/9807062 | | Services: | Forum | Review | PDF | Favorites | |
