Abstract

Let FP3F\subseteq\mathbb{P}^3 be a smooth quartic surface and let OF(h):=OP3(1)OF\mathcal{O}_F(h):=\mathcal{O}_{\mathbb{P}^3}(1)\otimes\mathcal{O}_F. In the present paper we classify locally free sheaves E\mathcal{E} of rank 22 on FF such that c1(E)=OF(2h)c_1(\mathcal{E})=\mathcal{O}_F(2h), c2(E)=8c_2(\mathcal{E})=8 and h1(F,E(th))=0h^1\big(F,\mathcal{E}(th)\big)=0 for tZt\in\mathbb{Z}. We also deal with their stability.
