Domain walls without cosmological constant in higher order gravity

We consider a class of higher order corrections in the form of Euler densities of arbitrary rank n to the standard gravity action in D dimensions. We present a generating functional and an explicit form of the conserved energy -momentum tensors. We show that this class of corrections allows for. domain-wall solutions despite the presence of higher; powers of the curvature. The existence of such solutions no longer depends on the presence of cosmological constants. For example, the Randall-Sundrum-type scenario can be realized without bulk and/or brane cosmslogical constant.
