Abstract

We define and study a concept of Hf -space for a map, which is a gener- alized concept of an H-space, in terms of the Gottlieb set for a map. For a principal fibration Ek ! X induced by k : X ! X′ from ǫ : PX′ ! X′, we can obtain a sufficient condition to having an H ¯ f -structure on Ek, which is a generalization of Stasheff’s result [17]. Also, we define and study a concept of co-Hg-space for a map, which is a dual concept of Hf -space for a map. Also, we get a dual result which is a generalization of Hilton, Mislin and Roitberg’s result [6].
