In addition, new equivalents of well-known formulas (O. Bonnet, Euler, Liouville) are found in this space. Finally, the examples of these surfaces are given.</dc:description><dc:publisher>University of Nis</dc:publisher><dc:date>2023</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/11446</dc:identifier><dc:identifier>https://doi.org/10.2298/fil2317735g</dc:identifier><dc:identifier>0354-5180</dc:identifier><dc:language>en</dc:language><dc:relation>Filomat</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/11446</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
