Extrinsic versus intrinsic diameter for Riemannian filling-discs and van Kampen diagrams
Riemannian filling-discs van Kampen diagrams
2015/8/26
The diameter of a disc filling a loop in the universal covering of a Riemannian manifold M may be measured extrinsically using the distance function on the ambient space or intrinsically using the ind...
Let G be a topological group. Then the based loopspace G of G is an algebra over the cacti operad, while the double loopspace 2BG of the classifying space of G is an algebra over the framed little dis...
