Higher Homotopy Commutativity of H-spaces with Finitely Generated Cohomology

چکیده
Suppose X is a simply connected mod p H-space such that the mod p cohomology H∗(X;Z/p) is finitely generated as an algebra. Our first result shows that if X is an An-space, then X is the total space of a principal An-fibration with base a finite An-space and fiber a finite product of CP∞s. As an application of the first result, it is shown that if X is a quasi Cp-space, then X is homotopy equivalent to a finite product of CP∞s.

Loop Spaces of H-spaces with Finitely Generated Cohomology
Let p be an odd prime. We assume that all spaces are completed at p in the sense of Bousfield-Kan [2], and the cohomologies are taken with Z/pcoefficients unless otherwise specified. In this paper, we investigate the homotopy type for the loop space of an H-space whose cohomology is finitely generated as an algebra. In the case of the cohomology is finite dimensional, there is the following the...
متن کاملHomotopy Exponents for Large H-spaces
We show that H-spaces with finitely generated cohomology, as an algebra or as an algebra over the Steenrod algebra, have homotopy exponents at all primes. This provides a positive answer to a question of Stanley.
متن کاملPacific Journal of Mathematics Loop Spaces of H-spaces with Finitely Generated Cohomology
Suppose X is a simply connected mod p H-space such that the mod p cohomology H ((X) is a nitely generated algebra. We show that the loop space X is homotopy equivalent to a nite product of Eilenberg-MacLane spaces K ; 1) for i 1. This is a generalization of the result due to Lin, in which the same result was proved under the assumption that X is an A p-space.
متن کاملDeconstructing Hopf Spaces
We characterize Hopf spaces with finitely generated cohomology as algebra over the Steenrod algebra. We “deconstruct” the original space into an Hspace Y with finite mod p cohomology and a finite number of p-torsion EilenbergMac Lane spaces. One reconstructs X from Y by taking extensions by principal H-fibrations. We give a precise description of homotopy commutative H-spaces in this setting an...
متن کاملHomotopical Uniqueness of Classifying Spaces
If G is a connected compact Lie group, then for almost all prime numbers p the mod p cohomology ring of the classifying space BG is a finitely generated polynomial algebra. In 1961, N. Steenrod [24] asked in general for a determination of all spaces X such that H∗(X,Fp) is a finitely generated polynomial algebra (i.e., such that X has a polynomial cohomology ring); at that time, the only exampl...
