Self-closeness numbers of finite cell complexes
Nobuyuki Oda, Toshihiro Yamaguchi
We reformulate the inequalities among self-closeness numbers of spaces in cofibrations making use of homology dimension and show that the self-closeness number of a space is less t…
Poset-stratified space structures of homotopy sets
Toshihiro Yamaguchi, Shoji Yokura
A poset-stratified space is a pair of a topological space and a continuous map with a poset considered as a topological space with its…
Sullivan minimal models of classifying spaces for non-formal spaces of small rank
Hirokazu Nishinobu, Toshihiro Yamaguchi
We consider certain rational homotopical conditions of simly connected CW complex such that the rational cohomology of the classifying space for fibrations with two-s…
A Hasse diagram for rational toral ranks
Toshihiro Yamaguchi
Let be a simply connected CW complex with finite rational cohomology. For the finite quotient set of rationalized orbit spaces of obtained by almost free toral actions, ${\…
A rational splitting of a based mapping space
Katsuhiko Kuribayashi, Toshihiro Yamaguchi
Let F_*(X, Y) be the space of base-point-preserving maps from a connected finite CW complex X to a connected space Y. Consider a CW complex of the form X cup_{alpha}e^{k+1} and a s…
