    An Introduction to the New Type of Globally Framed Manifold
    (American Institute Physics, 2017) Aktan, Nesip; Tekin, Pelin; Akdemir, AO; Ekinci, A.; Han, I.; Set, E.; Dadasoglu, F.; Karagoz, K.; Oztekin, A.
    The purpose of this paper is to give an introduction to new type of globally framed manifolds. Such manifolds are called globally framed nearly Sasakian manifolds. We show that a normal globally framed nearly Sasakian manifold is an S-manifold.

    B.Y. Chen's inequality for semi-slant submanifolds in T - Space forms
    (2008) Aktan, Nesip; Sarıkaya, Mehmet Zeki; Özüsa?lam, Erdal
    In this paper, B. Y. Chen inequality for semi-slant submanifolds in T - space forms are established by using subspaces orthogonal to the structure vector fields.

    Holomorphically Planar Conformal Vector Field On Almost alpha-Cosymplectic (kappa,mu)? Spaces
    (Fuat USTA, 2023) Yıldırım, Mustafa; Aktan, Nesip
    The aim of the present paper is to study holomorphically planar conformal vector (HPCV) fields on almost ????cosymplectic (?,?)?(?,?)?spaces. This is done assuming various conditions such as i) UU is pointwise collinear with ?? ( in this case, the integral manifold of the distribution DD is totally geodesic, or totally umbilical), ii) MM has a constant ????sectional curvature (under this condition the integral manifold of the distribution DD is totally geodesic (or totally umbilical) or the manifold is isometric to sphere S2n+1(?c)S2n+1(c) of radius 1?c1c), iii) MM an almost ????cosymplectic (?,?)?(?,?)?spaces ( in this case the manifold has constant curvature, or the integral manifold of the distribution DD is totally geodesic(or totally umbilical) or UU is an eigenvector of h).h).
