Abstract


This paper examines the quasi-conharmonic curvature tensor ˜H which generalizes
the concept of a conharmonic curvature tensor. Initially, we acquire some geometrical
features. Subsequently, we examine pseudo quasi-conharmonic symmetric
manifolds. The Divergence-free quasi-conharmonic curvature tensor is derived from
the Gray’s decomposition. Additionally, we also examine the nature of Einstein
(PQ ˜H S)n, (n > 2),manifolds. Finally, we construct a non-trivial Lorentzian metric
of (PQ ˜H S)4.
