Gluing Hyperconvex Metric Spaces

Benjamin Miesch (2015)

Analysis and Geometry in Metric Spaces

Similarity:

We investigate how to glue hyperconvex (or injective) metric spaces such that the resulting space remains hyperconvex. We give two new criteria, saying that on the one hand gluing along strongly convex subsets and on the other hand gluing along externally hyperconvex subsets leads to hyperconvex spaces. Furthermore, we show by an example that these two cases where gluing works are opposed and cannot be combined.

Strictly convex metric spaces with round balls and fixed points

Inese Bula (2005)

Banach Center Publications

Similarity:

The paper introduces a notion of strictly convex metric space and strictly convex metric space with round balls. These objects generalize the well known concept of strictly convex Banach space. We prove some fixed point theorems in strictly convex metric spaces with round balls.
