Our ultimate goal in this study is to concentrate on the convergence of the solutions to a predetermined constant by establishing a linkage between the delayed fractional differential equation and an integral equation. In our analysis, the sufficient conditions for the asymptotic results are obtained due to fixed point theory. The utilization of the contraction mapping principle is a convenient approach in obtaining technical conditions that guarantee the asymptotic constancy of the solutions.<\/jats:p>","DOI":"10.3390\/sym15010088","type":"journal-article","created":{"date-parts":[[2022,12,29]],"date-time":"2022-12-29T02:59:01Z","timestamp":1672282741000},"page":"88","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Asymptotic Constancy for the Solutions of Caputo Fractional Differential Equations with Delay"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8880-1552","authenticated-orcid":false,"given":"Halis Can","family":"Koyuncuo\u011flu","sequence":"first","affiliation":[{"name":"Department of Engineering Sciences, Izmir Katip Celebi University, Izmir 35620, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2154-9049","authenticated-orcid":false,"given":"Youssef","family":"Raffoul","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University of Dayton, 300 College Park, Dayton, OH 45469, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9012-4386","authenticated-orcid":false,"given":"Nezihe","family":"Turhan","sequence":"additional","affiliation":[{"name":"Department of Engineering Sciences, Izmir Katip Celebi University, Izmir 35620, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,29]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"M\u00e9moire sur quelques questions de g\u00e9om\u00e9trie et de m\u00e9canique, et sur un nouveau genre de calcul pour r\u00e9soudre ces questions","volume":"13","author":"Liouville","year":"1832","journal-title":"J.
