A geometry of the moduli space of Higgs pairs on an irreducible nodal curve of arithmetic genus one
arXiv:2305.18187
Abstract
We describe the moduli space of Higgs pairs on an irreducible nodal curve of arithmetic genus one and its geometric structures in terms of the Hitchin map and a flat degeneration of the moduli space of Higgs bundles on an elliptic curve.
