Dualities between K 3 fibered Calabi – Yau three - folds
We examine the relations of Calabi–Yau three-folds having the same Hodge numbers, (h, h) = (5, 185) with the various number of K3 fibers. We also argue their implications to string duality. [email protected]
متن کاملOn the Hodge structure of elliptically fibered Calabi-Yau threefolds
The Hodge numbers of generic elliptically fibered Calabi-Yau threefolds over toric base surfaces fill out the “shield” structure previously identified by Kreuzer and Skarke. The connectivity structure of these spaces and bounds on the Hodge numbers are illuminated by considerations from F-theory and the minimal model program. In particular, there is a rigorous bound on the Hodge number h21 ≤ 49...
متن کامل6D F-theory models and elliptically fibered Calabi-Yau threefolds over semi-toric base surfaces
We carry out a systematic study of a class of 6D F-theory models and associated Calabi-Yau threefolds that are constructed using base surfaces with a generalization of toric structure. In particular, we determine all smooth surfaces with a structure invariant under a single C∗ action (sometimes called “T-varieties” in the mathematical literature) that can act as bases for an elliptic fibration ...
متن کاملDualities between K 3 fibered Calabi – Yau three - folds with two
We propose a way to examine N=1 and N=2 string dualties on Calabi-Yau three-folds and their basis or extensions. Our way is to find out or to construct two types of toric representations of a Calabi-Yau three-fold, which contain phases of topologically equivalent or phases connected by flops. We discuss how to find relations among Calabi-Yau three-fold realized in different toric representation...
متن کاملGroup Representations and the Euler Characteristic of Elliptically Fibered Calabi–yau Threefolds
To every elliptic Calabi–Yau threefold with a section X there can be associated a Lie group G and a representation ρ of that group. The group is determined from the Weierstrass model, which has singularities that are generically rational double points; these double points lead to local factors of G which are either the corresponding A-D-E groups or some associated non-simply laced groups. The r...
