We show that for certain ranges of $a$, the $c$-parameter plane contains homeomorphic copies of the Mandelbrot set, as well as the $a$-plane for certain ranges of $c$. We use techniques first introduced by Douady and Hubbard, that were applied for the subfamily $R_{n,a,0}$ by Robert Devaney. These techniques involve polynomial-like maps of degree two.", "revisions": [ { "version": "v1", "updated": "2022-06-21T04:15:16.000Z" } ], "analyses": { "subjects": [ "37F10", "37F46" ], "keywords": [ "generalized mcmullen maps", "mandelbrot set", "parameter plane contains homeomorphic copies", "study rational functions" ], "note": { "typesetting": "TeX", "pages": 34, "language": "en", "license": "arXiv", "status": "editable" } } }
