Abstract
The aim of this work is to contribute to the classification of projective varieties according to their representation type, providing examples of n-dimensional varieties of wild representation type, for arbitrary n 2. More precisely, we prove that all Fano blow-ups of Pn at a finite number of points are of wild representation type exhibiting families of dimension of order r2 of simple (hence, indecomposable) ACM rank r vector bundles for any r n. In the two dimensional case, the vector bundles that we construct are moreover Ulrich bundles and μ-stable with respect to certain ample divisor.File | Dimensione | Formato | |
