bordant, by Hamrick-Royster. By Gromov-Ruh, almost flat manifolds are
infra-nilmanifolds. It is conjectured by Farrell-Zdravkovska that almost
flat manifolds are zero bordant (the same question was also collected in
Yau's problem list). In this talk I will explain some recent advances
joint with Jim Davis on this problem, asserting that the answer is yes
when the holonomy is cyclic. This generalizes earlier works of
Farrell-Zdravkovska and Upadhyay.
