Co-H-structures on equivariant Moore spaces
Let G be a finite group, OG the category of canonical orbits of G and A : OG → Ab a contravariant functor to the category of abelian groups. We investigate the set of G-homotopy classes of comultiplications of a Moore G-space of type (A, n) where n ≥ 2 and prove that if such a Moore G-space X is a cogroup, then it has a unique comultiplication if dimX < 2n − 1. If dimX = 2n − 1, then the set of...
متن کاملOn Certain Co–h Spaces Related to Moore Spaces
We show that certain co–H spaces, constructed by Anick and Gray, carry a homotopy co–associative and co–commutative co–H structure.
متن کاملON THE CAPACITY OF EILENBERG-MACLANE AND MOORE SPACES
K. Borsuk in 1979, at the Topological Conference in Moscow, introduced concept of the capacity of a compactum and asked some questions concerning properties of the capacity ofcompacta. In this paper, we give partial positive answers to three of these questions in some cases. In fact, by describing spaces homotopy dominated by Moore and Eilenberg-MacLane spaces, the capacities of a Moore space $...
متن کاملAxioms for Moore Spaces and Metric Spaces
for an arbitrary original polygon P . Further, no other relations Pn_p = 0 (p7*pi or p2 • or £jfc) are satisfied by P ' if P remains general ( P ' has no higher than the &th degree of regularity). This is also seen from (16'), where 0(co) ^ 0 , Rn-P^0 (since P is general) ; therefore P ' n _ ^ 0 . In fact, no relations of any kind besides (18) are satisfied by P' = MP if P remains general. This...
متن کاملcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
