A short elementary proof of Beben and Theriault's theorem on homotopy fibers
Daisuke Kishimoto, Yuki Minowa
Beben and Theriault proved a theorem on the homotopy fiber of an extension of a map with respect to a cone attachment, which has produced several applications. We give a short and…
Van Kampen-Flores theorem and Stiefel-Whitney classes
Daisuke Kishimoto, Takahiro Matsushita
The van Kampen-Flores theorem states that the -skeleton of a -simplex does not embed into . We prove the van Kampen-Flores theorem for triangulations of…
Tight complexes are Golod
Kouyemon Iriye, Daisuke Kishimoto
The Golodness of a simplicial complex is defined algebraically in terms of the Stanley-Reisner ring, and it has been a long-standing problem to find its combinatorial characterizat…
The space of commuting elements in a Lie group and maps between classifying spaces
Daisuke Kishimoto, Masahiro Takeda, Mitsunobu Tsutaya
Let be a discrete group, and let be a compact connected Lie group. Then there is a map between the null-components of…
Vector fields on non-compact manifolds
Tsuyoshi Kato, Daisuke Kishimoto, Mitsunobu Tsutaya
Let be a non-compact connected manifold with a cocompact and properly discontinuous action of a discrete group . We establish a Poincaré-Hopf theorem for a bounded vector fi…
Cellular cosheaf homology are cosheaf homology
Daisuke Kishimoto, Yasutomo Yushima
A cosheaf is the dual notion of a sheaf, but we cannot define its homology as the formal dual of sheaf cohomology, in general, because of the lack of the cosheafification. A cellul…
