Abstract
We give a method for producing examples of Calabi--Yau threefolds as covers of degree $d\le 8$ of almost--Fano threefolds, computing explicitely their Euler--Poincar\'e characteristic. Such a method generalizes the well--known classical construction of Calabi--Yau threefolds as double covers of the projective space branched along octic surfaces.File in questo prodotto:
