Abstract
The main purpose of the present paper is to study the geometric
properties of the conharmonic curvature tensor of normal locally conformal al-
most cosymplectic manifolds (normal LCAC-manifold). In particular, three con-
horonic invariants are distinguished with regard to the vanishing conharmonic
tensor. Subsequentaly, three classes of normal LCAC-manifolds are established.
Moreover, it is proved that the manifolds of these classes are -Einstein manifolds
of type ( , ). Furthermore, we have determined and for each class.
