| The Weak and Rather Weak Homotopy -Extension Property The aim of this paper is to compare the RWHEP (Theorem 3.2), we define and study several generalizations of homotopy equivalence maps. 1.INTRODUCTION The weak homotopy extension property (WHEP) of a pair of spaces (, A) is very important in problems involving relative homotopy equivalence (see for instance, Dold’s theorem [7], 2.18 ). R. Brown, in ( [1] pp. 255 ) considers weaker concept , the rather weak HEP (RWHEP) which is interesting for its applications in the fibrations of groupoids. The purpose of this paper is to compare the WHEP and RWHEP . Throughout this paper we work in the category of topological spaces and continuous maps . ( for definitions not given here see [3] ). | ||
