“…Almost complex structures and extensions of Norden structures on cotangent bundles of M were characterized by Nannicini ( [19] , [20] ) as being caused by complex structures on generalized tangent bundles of M . Various structures and metrics on the cotangent bundle are studied by numerous researches, Agcă [3] , Gezer and Altunbas [7] , Kankarej and Singh [14] , Ocak [21] , Salimov and Agcă [24] , Zagane et al [32] . Numerous geometries studied the tangent bundles on different manifolds and its submanifold with different connections and partial differential equations, which can be seen on ( [2] , [28] , [4] , [5] , [6] , [14] , [12] , [15] , [16] , [17] , [18] ).…”
