We start from an $\\mathcal{L}$-twisted Higgs bundle for some fixed holomorphic line bundle $\\mathcal{L}$ on the surface. We decorate the Higgs bundle with the choice of a section $s$ of $K^*\\otimes\\mathcal{L}$, where $K$ is the canonical line bundle, and then encode this data as a $b$-structure on the base Riemann surface which lifts to the associated Hitchin spectral curve. We then propose a so-called twisted topological recursion on the spectral curve, after which the corresponding Eynard-Orantin differentials live in a twisted cotangent bundle. This formulation retains, and interacts explicitly with, the singular structure of the original meromorphic setting -- equivalently, the zero divisor of $s$ -- while performing the recursion. Finally, we show that the $g=0$ twisted Eynard-Orantin differentials compute the Taylor expansion of the period matrix of the spectral curve, mirroring a result of Baraglia-Huang for ordinary Higgs bundles and topological recursion. Starting from the spectral curve as a polynomial form in an affine coordinate rather than a Higgs bundle, our result implies that, under certain conditions on $s$, the expansion is independent of the ambient space $\\mbox{Tot}(\\mathcal{L})$ in which the curve is interpreted to reside.", "revisions": [ { "version": "v1", "updated": "2024-01-12T16:59:48.000Z" } ], "analyses": { "subjects": [ "14D20", "70H06", "14A21" ], "keywords": [ "spectral curve", "twisted higgs bundle", "topological recursion", "eynard-orantin differentials", "works relating meromorphic higgs bundles" ], "note": { "typesetting": "TeX", "pages": 53, "language": "en", "license": "arXiv", "status": "editable" } } }
