Certain condition on the second fundamental form of CR submanifolds of maximal CR dimension of complex hyperbolic space

Studying the condition ({h(FX,Y)-h(X,FY)=g(FX,Y)eta, 0neetain T^perp(M)}) on the almost contact structure F and on the second fundamental form h of n-dimensional real submanifolds M of complex hyperbolic space ({mathbb {CH}^{frac{n+p}{2}}}) when their maximal holomorphic tangent subspace is (n ? 1)-dimensional, we obtain the complete classification of such submanifolds M and we characterize certain model spaces in complex hyperbolic space.
