We give some characterizations for such curves according to the Darboux frame, OD-frame, ND-frame, RD-frame, and obtain axes of the Di-Darboux slant helices. Moreover, the position vectors of the Di-Darboux slant helices are obtained.</dc:description><dc:publisher>Association of Mathematicians (MATDER)</dc:publisher><dc:date>2024</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/bayburt/12880</dc:identifier><dc:identifier>https://doi.org/10.47000/tjmcs.1310722</dc:identifier><dc:identifier>2148-1830</dc:identifier><dc:language>en</dc:language><dc:relation>Turkish Journal of Mathematics and Computer Science</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/12880</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
