A family of metrics on the moduli space of \(\mathbb{C} P^ 2\) instantons. (English) Zbl 0777.53038

A family of Riemannian metrics of the moduli space of irreducible selfdual connections of instanton number \(k=1\) over the complex projective plane is considered. The author finds explicit formulas for these metrics and defines conclusions concerning with geometry of the instanton space.
