Size homotopy groups for computation of natural size distances
The authors introduce and study a parametric family of groups (called by them size homotopy groups) for every manifold \(M\) endowed with a structure described by a function from \(M\) to the vector space \(\mathbb{R}^k\). Some lower bounds for natural size distances are obtained in this way.
