Let M be a simply connected complex submanifold of C . We prove that M is irreducible, up a totally geodesic factor, if and only if the normal holonomy group acts irreducibly. This is an extrinsic analogue of the well-known De Rham decomposition theorem for a complex manifold. Our result is not valid in the real context, as it is shown by many counter-examples.

Since their inception, social networking sites (SNSs) have experienced exponential growth.

We draw on theories of intrinsic and extrinsic motivation, and find that the prospect ...
