The purpose of this paper is
to introduce a variant of the geometric collapsing theory for Riemannian
manifolds contained in the joint work of J. Cheeger, K. Fukaya and M. Gromov
(henceforth called the “C-F-G-theory”). The authors make important use of this
variant geometric collapsing theory in Farrell and Jones, 1998(2), to develop
a theory for collapsing foliated Riemannian manifolds and then to prove
topological rigidity for certain aspherical manifolds in Farrell and Jones,
1998(1).
