摘要：
In this paper we investigate (epsilon, delta)-trans-Sasakian manifolds which generalize the notion of (epsilon)-Sasakian and (epsilon, delta)-Kenmotsu manifolds. We prove the existence of such a structure by an example and we consider phi-recurrent, pseudoprojectively flat and pseudo-projective semi-symmetric (epsilon, delta)-trans-Sasakian manifolds.
