Abstract
In [2] 2009 some quotients of one-parameter families of CalabiYau varieties are related to the family of Mirror Quintics by using a construction due to Shioda. In this paper, we generalize this construction to a wider class of varieties. More specifically, let A be an invertible matrix with non-negative integer entries. We introduce varieties XA and MA an weighted projective space and in, respectively. The variety turns out to be a quotient of a Fermat variety by a finite group. As a by-product, XA is a quotient of a Fermat variety and is a quotient of XA by a finite group. We apply this construction to some families of CalabiYau manifolds in order to show their birationality.Pubblicazioni consigliate
