Abstract:
For totally real complete space-like submanifolds in indefinite complex space form, the problem of establishing geometric inequalities between the intrinsic invariants
δ (
n1,
n2, …,
nk) and the extrinsic invariants (square of the mean curvature) was studied. The inequalities about
δ(2) and
δ(
n1,
n2, …,
nk) of time-like and space-like geodesic submanifolds in the indefinite complex space were established by algebraic inequalities and moving frame methods, and the
δinequality for totally real complete space-like submanifolds in indefinite complex space form was obtained.
