The 2-components of the 31-stem homotopy groups of the 9 and 10-spheres
arXiv:1210.0995
Abstract
Group structures of the 2-primary components of the 31-stem homotopy groups of spheres were studied by Oda in 1979. There are, however, two incompletely determined groups. In this paper, our investigation with Toda's composition method gives structures of them.
