Abstract
We show that there exist smooth surfaces violating Generic Vanishing in any characteristic \(p \ge 3\). As a corollary, we recover a result of Hacon and Kovács, producing counterexamples to Generic Vanishing in dimension 3 and higher.

Notes
In the following, we will consider with L ample. In this case, we will have \(i(M)=\dim B\), and \(|\chi (M)|=h^0(L)\).
