Here, we obtain a fixed point theorem for interpolative Rus\u2013Reich\u2013\u0106iri\u0107 contraction mappings in the realm of rectangular quasi-partial b-metric spaces. Furthermore, an example is also illustrated to present the applicability of our result.<\/jats:p>","DOI":"10.3390\/sym13010032","type":"journal-article","created":{"date-parts":[[2020,12,28]],"date-time":"2020-12-28T20:03:03Z","timestamp":1609185783000},"page":"32","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Fixed Point of Interpolative Rus\u2013Reich\u2013\u0106iri\u0107 Contraction Mapping on Rectangular Quasi-Partial b-Metric Space"],"prefix":"10.3390","volume":"13","author":[{"given":"Pragati","family":"Gautam","sequence":"first","affiliation":[{"name":"Department of Mathematics, Kamala Nehru College, University of Delhi, New Delhi 110049, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7559-6724","authenticated-orcid":false,"given":"Luis Manuel","family":"S\u00e1nchez Ruiz","sequence":"additional","affiliation":[{"name":"ETSID-Departamento de Matematica Aplicada &amp; CITG, Universitat Politecnica de Valencia, E-46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2041-3334","authenticated-orcid":false,"given":"Swapnil","family":"Verma","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Kamala Nehru College, University of Delhi, New Delhi 110049, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,28]]},"reference":[{"key":"ref_1","first-page":"71","article-title":"Some results on fixed points","volume":"60","author":"Kannan","year":"1968","journal-title":"Bull.
