Item Almost f-cosymplectic manifolds(Springer, 2014-05) Aktan, Nesip; Yıldırım, Mustafa; Murathan, Cengizhan; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Bölümü.; ABE-8167-2020; 6506718146The purpose of this paper is to study a new class of contact manifolds. Such manifolds are called almost f-cosymplectic manifolds. Several tensor conditions are studied for such type of manifolds. We conclude our results with two examples of almost f-cosymplectic manifolds.Item Almost α-cosymplectic f-manifolds(Univ Al I Cuza, 2014) Öztürk, Hakan; Aktan, Nesip; Turgut Vanlı, Aysel; Murathan, Cengizhan; Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Matematik Bölümü.; ABE-8167-2020; 6506718146The purpose of this paper is to study a new class of framed manifolds. Such manifolds are Called almost alpha-cosymplectic f-manifolds. For some special cases of alpha and s, one obtains (almost) alpha-cosymplectic, (almost) C-manifolds, and (almost) Kenmotsu f-manifolds. Moreover, several tensor conditions are studied. We conclude our results with a general example on alpha-cosymplectic f-manifolds.
