Moraru, Ruxandra Integrable systems associated to a Hopf surface. (English) Zbl 1058.37043 Can. J. Math. 55, No. 3, 609-635 (2003). Moduli spaces \({\mathcal M}^{n}\) of stable \(\text{SL}(2,{\mathbb C})\)-bundles on a Hopf surface \({\mathcal H}\) are studied from the point of view of non-Kählerian elliptic fibrations. More precisely, a map \(G:{\mathcal M}^{n}\rightarrow P^{2n+1}\) that associates to every bundle on \({\mathcal H}\) a divisor, called the graph of the bundle, which encodes the isomorphism class of the bundle over each elliptic curve, is defined. The main result is that \(G\) yields an algebraically completely integrable Hamiltonian system with respect to a given Poisson structure on \({\mathcal M}^{n}\) and an explicit description of the fibres of this integrable system is given.
