In recent years, the Penrose twistor transform has been extensively and successfully used to convert certain problems arising in physics into problems of algebraic geometry [the author, Geometry of Yang-Mills fields (Pisa 1979; Zbl 0435.58001)]. More precisely, solutions of the self-dual Yang-Mills equations on \({\mathbb{R}}^ 4\) (describing ‘instantons’) convert into holomorphic bundles on the complex projective 3-space \({\mathbb{P}}^ 3\). Similarly, solutions of the Bogomolny equation in \({\mathbb{R}}^ 3\) (describing ‘magnetic monopoles’) convert into holomorphic bundles on \(T{\mathbb{P}}_ 1\) (the tangent bundle of \({\mathbb{P}}_ 1)\) [N. J. Hitchin, Commun. Math. Phys. 83, 579-602 (1982; Zbl 0502.58017)]. In this talk, I shall consider the analogous problem, for magnetic monopoles, when the Euclidean 3-space \({\mathbb{R}}^ 3\) is replaced by the hyperbolic 3-space \(H^ 3\). Twistor methods still apply and so then ‘hyperbolic monopoles’ can also be described by holomorphic bundles.
