n-Dimensional Fano varieties of wild representation type

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 P-n at a finite number of points are of wild representation type exhibiting families of dimension of order r(2) 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 mu-stable with respect to certain ample divisor. (C) 2014 Elsevier B.V. All rights reserved.
