Abstract
This paper studies the contact CR-warped product submanifolds of a generalized Sasakian space form admitting a nearly cosymplectic structure. Some inequalities for existence of these types of warped product submanifolds are established, the obtained inequalities generalize the results that have acquired in [14]. Moreover, we also estimate another inequality for the second fundamental form in the expressions of the warping function, this inequality also generalize the inequalities that have obtained in [19]. In addition, we also explore the equality cases.
