 Examples of smooth surfaces in $\mathbb{P}^3$ which are Ulrich--wild Bull. Korean Math. Soc. 2017 Vol. 54, No. 2, 667-677 https://doi.org/10.4134/BKMS.b160257Published online March 31, 2017 Gianfranco Casnati Politecnico di Torino Abstract : Let $F\subseteq\mathbb{P}^3$ be a smooth surface of degree $3\le d\le 9$ whose equation can be expressed as either the determinant of a $d\times d$ matrix of linear forms, or the pfaffian of a $(2d)\times (2d)$ matrix of linear forms. In this paper we show that $F$ supports families of dimension $p$ of pairwise non-isomorphic, indecomposable, Ulrich bundles for arbitrary large $p$.
