On CR-submanifolds of a certain class of almost contact manifolds. (English) Zbl 0824.53054
CR-submanifolds of a Kenmotsu manifold were investigated by {\it N. Papaghiuc} [Rend. Mat. Appl., VII. Ser. 3, 607-622 (1983; Zbl 0541.53010)] and {\it M. Kobayashi} [Tensor, New Ser. 43, 28-36 (1986; Zbl 0608.53050)]. The author obtains new results on contact CR-products and sectional curvatures of CR-submanifolds of a Kenmotsu manifold.
