Lusternik-Schnirelmann category of Spin{9}
Norio Iwase, Akira Kono
Let G be a compact connected Lie group and p : E \to Σ^2V a principal G-bundle with a characteristic map α: A=ΣV \to G. By combining cone decomposition arguments in Iwase-Mimura-Ni…
Splitting off Rational Parts in Homotopy Types
Norio Iwase, Nobuyuki Oda
It is known algebraically that any abelian group is a direct sum of a divisible group and a reduced group (See Theorem 21.3 of \cite{Fuchs:abelian-group}). In this paper, condition…
Lusternik-Schnirelmann categories of non-simply connected compact simple Lie groups
Norio Iwase, Mamoru Mimura, Tetsu Nishimoto
Let be a fibre bundle with structure group , where is -connected and of finite dimension, . We prove that the strong L-S categ…
On the cellular decomposition and the Lusternik-Schnirelmann category of
Norio Iwase, Mamoru Mimura, Tetsu Nishimoto
We give a cellular decomposition of the compact connected Lie group . We also determine the L-S categories of and .
L-S categories of simply-connected compact simple Lie groups of low rank
Norio Iwase, Mamoru Mimura
We determine the L-S category of Sp(3) by showing that the 5-fold reduced diagonal $\widebarΔ_5$ is given by , using a Toda bracket and a generalised cohomology theory g…
A p-complete version of the Ganea Conjecture for co-H-spaces
J. R. Hubbuck, Norio Iwase
A finite connected CW complex which is a co-H-space is shown to have the homotopy type of a wedge of a bunch of circles and a simply-connected finite complex after almost -compl…
