Some geometric properties of these surfaces such as striction curves, surface normal vectors, tangent and asymptotic planes, distribution parameters, Gaussian and mean curvatures and fundamental forms are investigated. Some results and interpretations of these surfaces are obtained.</dc:description><dc:publisher>Maejo University</dc:publisher><dc:date>2025</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/11655</dc:identifier><dc:identifier>1905-7873</dc:identifier><dc:language>en</dc:language><dc:relation>Maejo International Journal of Science and Technology</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/11655</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
