algebraic topology – application of higher algebra and higher category theory to the study of (stable) homotopy theory
The operations on an H-space equip its homology with the structure of ring. At least for ordinary homology this is known as the Pontrjagin ring of .
The homological version of the group completion theorem relates the Pontrjagin ring of a topological monoid to that of its group completion .
