It is proved that a conformal flat normal metric contact pair manifold is an Einstein manifold with a positive scalar curvature and has positive sectional curvature. It is also shown that a concircular flat normal metric contact pair manifold is an Einstein manifold. Finally, it is obtained that a quasi-conformally flat normal metric contact pair manifold is an Einstein manifold with a positive scalar curvature and, is a space of constant curvature.</dc:description><dc:publisher>ANKARA UNIV, FAC SCI</dc:publisher><dc:date>2020</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/munzur/4912</dc:identifier><dc:identifier>https://doi.org/10.31801/cfsuasmas.546701</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://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/4912</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
