The group of homotopy self-equivalences is a Lax functor
Toshihiro Yamaguchi, Shoji Yokura
The group $\E(X)$ of homotopy self-equivalences of a topological space is a well-known group in homotopy theory and has been studied by many people since it was first introduce…
A co-operational bivariant theory derived from cohomology operations
Shoji Yokura
A co-operational bivariant theory is a ``dual" version of Fulton--MacPherson's operational bivaiant theory. For a given contravariant functor we define a generalized cohomology ope…
Hilali conjecture and complex algebraic varieties
Shoji Yokura
A simply connected topological space is called \emph{rationally elliptic} if the rank of its total homotopy group and its total (co)homology group are both finite. A well-known Hil…
On stratifications and poset-stratified spaces
Lukas Waas, Jon Woolf, Shoji Yokura
A stratified space is a topological space equipped with a \emph{stratification}, which is a decomposition or partition of the topological space satisfying certain extra conditions.…
Co-operational bivariant theory
Shoji Yokura
For a covariant functor W. Fulton and R. MacPherson defined \emph{an operational bivariant theory} associated to this covariant functor. In this paper we will show that given a con…
A bi-variant algebraic cobordism via correspondences
Shoji Yokura
A bi-variant theory defined for a pair is a theory satisfying properties similar to those of Fulton--MacPherson's bivariant theory $\mathbb B(X \xrightarro…
