It is well known that Minsky's primitive-stable representations form a domain of discontinuity for the $\\text{Out}(F_n)$-action on the $\\text{PSL}(2,\\mathbb{C})$-character variety. We define simple-stability of representations of fundamental group of a surface into $\\text{PSL}(2,\\mathbb{R})$ which is an analogue of the definition of primitive stability and prove that these representations form a domain of discontinuity for the $\\text{MCG}$-action. Our first main result shows that holonomies of hyperbolic cone surfaces are simple-stable. We also prove that holonomies of hyperbolic cone surfaces with exactly one cone-point of cone-angle less than $\\pi$ are primitive-stable, thus giving examples of an infinite family of indiscrete primitive-stable representations.", "revisions": [ { "version": "v1", "updated": "2025-02-13T17:29:30.000Z" } ], "analyses": { "keywords": [ "mapping class group action", "character variety", "hyperbolic cone surfaces", "minskys primitive-stable representations form", "first main result" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable" } } }
