Moduli of autodual instanton bundles. (English) Zbl 1371.14017

Authors’ abstract: We provide a description of the moduli space of framed autodual instanton bundles on \(\mathbb {P}^n\), focusing on the particular cases of symplectic and orthogonal instantons. Our description will use the generalized ADHM equations which define framed instanton sheaves. There are description theorems (the objects are in a bijection with something else) and as an application non-existence results, e. g. the non-existence of orthogonal instanton bundles on \(\mathbb {P}^n\) of trivial splitting type, arbitrary rank \(r\), and charge \(2\). The introduction and the references are very helpful.
