Also in this work, we present a complete connected nearly cosymplectic manifold is M–projectively flat if and only if it is either isometric to the sphere Sn or the real projective space.en10.5958/1945-919X.2019.00004.5info:eu-repo/semantics/closedAccessContact ManifoldsCosymplectic ManifoldsNearly Cosymplectic manifoldsArticle1051
