RT Journal Article T1 Some homotopy properties of FANR spaces (Spanish) A1 Rodríguez Sanjurjo, José Manuel AB 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.
