It provides a complete topological classification of collapsing 3D Alexandrov spaces with boundary, advancing understanding of their geometric structure.
Findings
Topological types identified for collapsing spaces
Extension of classification to spaces with boundary
New insights into boundary effects on collapse
Abstract
As a continuation of [MY], we determine the topologies of collapsing three-dimensional compact Alexandrov spaces with nonempty boundary.
