These concepts usually differ in the number of self-inverse colors used. We introduce a unifying concept for this kind of coloring by assigning elements from symmetric sets to the vertices of the signed graphs. In the first part of the paper, we study colorings with elements from symmetric sets where the number of self-inverse elements is fixed. We prove a Brooks’-type theorem and upper bounds for the corresponding chromatic numbers in terms of the chromatic number of the underlying graph. These results are used in the second part where we introduce the symset-chromatic number χsym(G,σ) of a signed graph (G,σ). We show that the symset-chromatic number gives the minimum partition of a signed graph into independent sets and non-bipartite antibalanced subgraphs. In particular, χsym(G,σ)≤χ(G). In the final section we show that these colorings can also be formalized as DP-colorings."}],"date_created":"2022-10-17T07:54:41Z","external_id":{"arxiv":["2106.05928"]},"department":[{"_id":"542"}],"type":"journal_article","keyword":["Discrete Mathematics and Combinatorics"]},{"doi":"10.1007/s00373-022-02506-x","language":[{"iso":"eng"}],"article_number":"104","intvolume":"        38","publication_status":"published","date_updated":"2023-05-16T10:41:42Z","author":[{"full_name":"Steffen, Eckhard","orcid":"0000-0002-9808-7401","last_name":"Steffen","first_name":"Eckhard","id":"15548"},{"full_name":"Wolf, Isaak Hieronymus","last_name":"Wolf","first_name":"Isaak Hieronymus","id":"88145"}],"publication_identifier":{"issn":["0911-0119","1435-5914"]},"year":"2022","title":"Even Factors in Edge-Chromatic-Critical Graphs with a Small Number of Divalent Vertices","type":"journal_article","keyword":["Discrete Mathematics and Combinatorics","Theoretical Computer Science"],"date_created":"2022-05-31T06:13:57Z","issue":"3","publication":"Graphs and Combinatorics","volume":38,"user_id":"15540","_id":"31543","publisher":"Springer Science and Business Media LLC","status":"public","external_id":{"arxiv":["2109.11447"]},"citation":{"chicago":"Steffen, Eckhard, and Isaak Hieronymus Wolf. “Even Factors in Edge-Chromatic-Critical Graphs with a Small Number of Divalent Vertices.” <i>Graphs and Combinatorics</i> 38, no. 3 (2022). <a href=\"https://doi.org/10.1007/s00373-022-02506-x\">https://doi.org/10.1007/s00373-022-02506-x</a>.","short":"E.
