Özet

The aim of this study is to explore the complete lifts of almost Norden structures on tangent bundles of Walker four-manifolds. Furthermore, we examine the integrability conditions of the complete lifts JC of the proper almost complex structure and identify the conditions for the isotropic Kähler-Norden property of the structure JC on (T (M4), JC, gC). Finally, we investigate the holomorphic conditions of the Norden (Kähler-Norden) metrics gC and discuss Quasi-Kähler-Norden metrics gC on the tangent bundle (T (M4), φC, gC) of Walker four-manifolds.
