Pre-c-symplectic condition for the product of odd-spheres

Junro Sato, Toshihiro Yamaguchi

We say that a simply connected space $X$ is pre-c-symplectic if it is the fibre of a rational fibration $X\to Y\to \C P^{\infty}$ where $Y$ is cohomologically symplectic in the sen…

Examples of rational toral rank complex

Toshihiro Yamaguchi

In "A Hosse diagram for rational toral tanks," we see a CW complex $T (X)$ , which gives a rational homotopical classification of almost free toral actions on spaces in th…

A relaxed evaluation subgroup

Toshihiro Yamaguchi

Let $f : X \to Y$ be a pointed map between connected CW-complexes. As a generalization of the evaluation subgroup $G_{*} (Y, X; f)$ , we will define the {\it relaxed evaluation subgroup} ${…

A rational obstruction to be a Gottlieb map

Toshihiro Yamaguchi

We investigate {\it Gottlieb map}s, which are maps $f : E \to B$ that induce the maps between the Gottlieb groups $π_{n} (f) ∣_{G_{n} (E)} : G_{n} (E) \to G_{n} (B)$ for all $n$ , from a rational hom…
