abstract = {In the present paper we study Ricci pseudo-symmetry, Z-Ricci pseudo-symmetry and concircularly pseudo-symmetry conditions on a mixed generalized quasi-Einstein spacetime    M  G  (  Q  E      )          4      . Also, it is proven that if    d  ≠  Λ, then    M  G  (  Q  E      )          4       spacetime does not admit heat flux, where    d and    Λ are the function and the cosmological constant, respectively. In the end of this paper we construct a non-trivial example of    M  G  (  Q  E      )          4       to prove its existence.}
