In particular, we give a complete characterization of possible eigenvalues for these operators and solve the inverse spectral problem of reconstructing the perturbation from the resulting spectrum. This approach provides a unified treatment of several recent studies and gives a clear explanation and interpretation of the obtained results.<\/jats:p>","DOI":"10.3390\/axioms11010024","type":"journal-article","created":{"date-parts":[[2022,1,9]],"date-time":"2022-01-09T20:29:26Z","timestamp":1641760166000},"page":"24","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Reconstruction of Differential Operators with Frozen Argument"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8372-2943","authenticated-orcid":false,"given":"Oles","family":"Dobosevych","sequence":"first","affiliation":[{"name":"Faculty of Applied Sciences, Ukrainian Catholic University, 79026 Lviv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0394-9791","authenticated-orcid":false,"given":"Rostyslav","family":"Hryniv","sequence":"additional","affiliation":[{"name":"Faculty of Applied Sciences, Ukrainian Catholic University, 79026 Lviv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"429","DOI":"10.1515\/jiip-2018-0047","article-title":"On recovering a Sturm\u2014Liouville-type operator with the frozen argument rationally proportioned to the interval length","volume":"27","author":"Buterin","year":"2019","journal-title":"J.
