The MAF Rigidity Conjecture for approximate fibrations

Let BB be a closed aspherical manifold, and let p ⁣:MBp\colon M\to B and q ⁣:NBq\colon N\to B be MAFs. MAF Rigidity Conjecture. The maps pp and qq are controlled homeomorphic if and only if there is a homeomorphism h ⁣:MNh\colon M\to N such that qhq\circ h is homotopic to pp. This is a rigidity statement asserting that the controlled-homeomorphism classification of MAFs is determined by the corresponding ordinary homotopy data. The supplied passage attributes the conjecture to Hughes, Taylor, and Williams and gives no indication that it has been resolved.
