Four-dimensional submanifolds of seven-dimensional almost contact manifolds with B-metric
Aspects of Complex Analysis, Diff. Geometry, Math. Physics and Applications, World Sci. Publ., Singapore, 148-159
In this paper we consider classes of 7-dimensional almost contact manifolds with B-metric, constructed as a direct product of 4-dimensional almost complex manifolds with B-metric and 3-dimensional almost contact manifolds with B-metric. Four-dimensional submanifolds of 7-dimensional almost contact manifolds with B-metric are studied and examples of such submanifolds are constructed.
