The relative James construction and its application to homotopy groups

Zhongjian Zhu, Tian Jin

In this paper, we develop the new method to compute the homotopy groups of the mapping cone $C_{f} = Y \cup_{f} C X$ beyond the metastable range by analysing the homotopy of the $n$ -th fi…

The $n + 3$ , $n + 4$ dimensional homotopy groups of $A_{n}^{2}$ -complexes

Tian Jin, Zhongjian Zhu

In this paper, we calculate the $n + 3$ , $n + 4$ dimensional homotopy groups of indecomposable $A_{n}^{2}$ -complexes after localization at 2. This job is seen as a sequel to P.J.…
