Weighted homology theory of orbifolds and Weighted Polyhedra
Yin Wei, Lisu Wu, Li Yu
We introduce two new homology theories of orbifolds from some special type of triangulations adapted to an orbifold, called AW-homology and DW-homology. The main idea in the defini…

A unifying view toward polyhedral products through panel structures
Li Yu
A panel structure on a topological space is just a locally finite family of closed subspaces. A space together with a panel structure is called a space with faces. In this paper, w…
