Abstract
In this paper the author studies homotopy properties of FANR spaces (fundamental absolute neighborhood retracts). The principal result is a theorem about homotopy extensions for fundamental ε -near sequences such that the initial and final levels of the extension coincide with previously determined fundamental sequences. The author conjectures that this property characterizes FANR spaces.
