Singular moduli spaces of stable vector bundles on \(\mathbb{P}^ 3\)
The goal of the paper is to give an example of a singular moduli space of rank-3 stable vector bundles on \(\mathbb{P}_3\). The main theorem asserts that \(M(3;-1, 14609, 1917791)\) is singular. Here \(M(3;c_1,c_2,c_3)\) is the moduli scheme of Maruyama for stable rank-3 vector bundles on \(\mathbb{P}_3\) with Chern classes \(c_1,c_2,c_3\).
