Trees (topology) | Metric geometry
A geodesic metric space is called tree-graded space, with respect to a collection of connected proper subsets called pieces, if any two distinct pieces intersect by at most one point, and every non-trivial simple geodesic triangle of is contained in one of the pieces. Thus, for pieces of bounded diameter, tree-graded spaces behave like real trees in their coarse geometry (in the sense of Gromov), while allowing non-tree-like behavior within the pieces. Tree-graded spaces were introduced by Cornelia Druţu and Mark Sapir in their study of the asymptotic cones of hyperbolic groups. (Wikipedia).

We present a new approach to regularity structures, and in particular to the construction of the structure group, which replaces the tree-based framework of Hairer by a more Lie-geometric setting. We consider the space of pairs (a,p), where a is a placeholder for the nonlinearity and p is

Gunnar Carlsson (6/26/17) Bedlewo: Local to global principles for persistent homology
One could say that the goal of topology is to formulate “local to global principles”. Such principles have not been discussed a great deal within the applied topology/persistent homology world. I will discuss some results and questions in this direction, including excision and Künneth form
