We generalize the mechanism proposed in [hep-th/0005016] and show that a-dimensional relativistic tensor theory of gravitation can be obtained on a-function brane in flat infinite-volume extra space. In particular, we that the induced Ricci scalar gives rise to Einstein's gravity on a-function type brane if the number of space-time dimensions is bigger than. The bulk space exhibits the phenomenon of infrared transparency. That is say, the bulk can be probed by gravitons with vanishing four-dimensional square, while it is unaccessible to higher modes. This provides an framework for solving the cosmological constant problem.
