In this paper we prove some new fixed point theorems in r -normed and locally r -convex spaces. Our conclusions generalize many well-known results and provide a partial affirmative answer to Schauder’s conjecture. Based on the obtained results, we prove the analogue of a Von Neumann’s theorem in locally r -convex spaces. In addition, an application to game theory is presented.","PeriodicalId":51051,"journal":{"name":"Fixed Point Theory","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44006742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hölder continuous first derivative is used to extend the applicability of the method on such problems for which Lipschitz condition fails.
