Abstract. In this talk I will discuss the role of the non-branching assumption in MCP(K,N)
and CD(K,N) spaces via examples that are subsets of the plane with the supremum norm.
The focus will be on the local-to-global property, splitting and maximal diameter theo-
rems, dimensions, tangents and existence of optimal transport maps. Part of the results
are joint work with Christian Ketterer
