This criterion extends the findings previously reported by Jiang (2004), Pervova-Petronio (2006), Zhu (2019), and Wei-Wu-Xu (2024). Furthermore, as an application of our criterion, we introduce several novel exceptional branching datum.", "revisions": [ { "version": "v2", "updated": "2024-12-02T07:30:53.000Z" } ], "analyses": { "subjects": [ "57M12" ], "keywords": [ "branched covers", "novel exceptional branching datum", "complex analysis", "specific types", "criterion extends" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable" } } }
