摘要：We study the construction of e
ective theories at distances much longer
than the transverse size of ve dimensional non-factorizable geometries. An observer
unable to resolve the transverse direction can only measure distances along the parallel
dimensions, but the non-factorizable geometry makes the length of a curve along the
parallel dimension sensitive to where on the transverse direction the curve lies. We show
that all long geodesics that di
er in their endpoints only by shifts along the transverse
direction have the same length to within the observer's resolution. This allows us to
present a consistent interpretation of what is measured by observers that live either on a
brane or in the bulk.
