| چکیده | ||
| The (n +1)-dimensional almost metric contact submanifolds wuth maximal CR- submanifolds of (n-1) in the Kenmotsu space forms classified such that n > 5 and h(FX, Y )-h(X, FY )= g(FX,Y)ζ for vector fields X, Y tangent to M, where h and F denote the second fundamental form and a skew-symmetric endomorphism acting on the tangent space of M, respectively, and ζ a non zero normal vector field to M. | ||
