We show that solvable Leibniz algebras with abelian nilradicals, which have [Formula: see text] dimension complementary space, admit local derivations which are not derivations. Moreover, similar problem concerning [Formula: see text]-local derivations of such algebras is investigated and an example of solvable Leibniz algebra is given such that any [Formula: see text]-local derivation on it is a derivation, but which admits local derivations which are not derivations. <\/jats:p>","DOI":"10.1142\/s021819672050037x","type":"journal-article","created":{"date-parts":[[2020,3,16]],"date-time":"2020-03-16T15:53:48Z","timestamp":1584374028000},"page":"1185-1197","source":"Crossref","is-referenced-by-count":21,"title":["Local and 2-local derivations of solvable Leibniz algebras"],"prefix":"10.1142","volume":"30","author":[{"given":"Shavkat","family":"Ayupov","sequence":"first","affiliation":[{"name":"V.
