A "Periodicity" Phenomenon of the Attaching Map of the Suspended Two-Cell Complex

Juxin Yang, Fengchun Lei, Jingyan Li +1

In this paper, we determine the 3-cell skeleton of $F$ , where $F$ is the homotopy fiber of the canonical pinch map from a suspension of a simply-connected 2-cell complex onto a sph…

On the extension problems for three 33-stem homotopy groups

Juxin Yang, Jie Wu

This paper tackles the extension problems for three far-unsatble homotopy groups $π_{39} (S^{6})$ , $π_{40} (S^{7})$ , and $π_{41} (S^{8})$ localized at 2, the puzzles having remained u…

On rectangular Toda brackets and Oda's extension problems

Juxin Yang, Jie Wu

This paper tackles \textit{N. Oda}'s extension problems for the homotopy groups $π_{39} (S^{6})$ , $π_{40} (S^{7})$ , and $π_{41} (S^{8})$ localized at 2, the issues having eluded resol…
