REPRESENTATION THEORY IN HOMOTOPY AND THE EHP SEQUENCES FOR (p− 1)-CELL COMPLEXES

چکیده

For spaces localized at 2, the classical EHP fibrations [1, 13] ΩS S ΩS ΩS play a crucial role for the computations of the homotopy groups of the spheres [16, 25]. The EHP-fibrations for (p− 1)-cell complexes for p > 2 are given in this article. These fibrations can be regarded as the odd prime analogue of the classical EHP-fibrations by considering the spheres as 1-cell complexes for p = 2. Some fundamental results on the theory of natural coalgebra decompositions of tensor algebras are established in this article. As a consequence of the study on the representation theory in homotopy, the new EHP-fibrations are obtained from the evaluations of the functor Amin on (p − 1)-cell complexes. An application to H-spaces is also given.

Thesis Proposal: Periodic Homotopy Theory of Unstable Spheres

The unstable homotopy groups of spheres can be approached by the EHP spectral sequence. There are computations of the low dimensional portion of the EHP sequence by Toda [1, 2] for the 2,3-primary part, and Behrens [3], Harper [4] for the 5-primary part. There are certain stable phenomenon in the EHP sequence. In fact, there is one portion in the E1-term which are in the stable range, which mea...

The Goodwillie tower and the EHP sequence

We study the interaction between the EHP sequence and the Goodwillie tower of the identity evaluated at spheres at the prime 2. Both give rise to spectral sequences (the EHP spectral sequence and the Goodwillie spectral sequence, respectively) which compute the unstable homotopy groups of spheres. We relate the Goodwillie filtration to the P map, and the Goodwillie differentials to the H map. F...

The Root Invariant in Homotopy Theory

For the last thirty years the EHP sequence has been a major conceptual tool in the attempt to understand the homotopy groups of spheres. It is a collection of long exact sequences of homotopy groups induced by certain fibrations in which all three spaces are loop spaces of spheres. These fibrations are due originally to James, G. W. Whitehead, and Toda. The Freudenthal suspension theorem and th...

Natural Decompositions of Self-smashes of 2-cell Complexes

Let X be a path-connected p-local CW -complex and let X be the n-fold self smash product of X. Decompositions of ΣX have been largely studied (See for instance [11, 19, 21, 22, 27].) with various applications in homotopy theory such as the exponents problem of homotopy groups [3, 4, 5], Morava K-theory [17, 22] and Steenrod modules [27]. For a general space X, a natural way to study decompositi...

Exact Sequences of Fibrations of Crossed Complexes, Homotopy Classification of Maps, and Nonabelian Extensions of Groups

The classifying space of a crossed complex generalises the construction of Eilenberg-Mac Lane spaces. We show how the theory of fibrations of crossed complexes allows the analysis of homotopy classes of maps from a free crossed complex to such a classifying space. This gives results on the homotopy classification of maps from a CW -complex to the classifying space of a crossed module and also, ...
