Research Memo



This page include some memo's about homotopy theory.
Hopf spaces are fundamental objects of interest in homotopy theory, and the projective plane of a Hopf space is also fundamental. But usually it is defined as a mapping cone of a map from a mapping cone and not easy to comprehend for beginners.

Moreover, more general objects projective n-space of a associative Hopf space is also defined. Is there any more comprehensive definition of projective n-spaces? See this.
