Then, we construct new ruled surfaces along these Smarandache curves with the direction vectors obtained from the Frenet vectors and the Darboux vector, and give the equations of these surfaces. In addition, we calculate the Gaussian and mean curvatures of these surfaces separately and present the conditions to be minimal and developable for these surfaces. Finally, as an example, we obtain ruled surfaces whose base curves are Viviani’s curves and plot the graphics of these surfaces.</dc:description><dc:publisher>Ankara University Faculty of Science</dc:publisher><dc:date>2023</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/14564</dc:identifier><dc:identifier>https://doi.org/10.31801/cfsuasmas.1151064</dc:identifier><dc:identifier>1303-5991</dc:identifier><dc:language>en</dc:language><dc:relation>Communications Faculty of Sciences University of Ankara Series A1 Mathematics and Statistics</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/14564</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
