Band width and the Rosenberg index
Yosuke Kubota
A Riemannian manifold is said to have infinite -width if it admits an isometric immersion of an arbitrarily wide Riemannian band whose inward boundary has non-trivial…
The bulk-dislocation correspondence for weak topological insulators on screw-dislocated lattices
Yosuke Kubota
A weak topological insulator in dimension is known to have a topologically protected gapless mode along the screw dislocation. In this paper we formulate and prove this fact wi…
Codimension 2 transfer of higher index invariants
Yosuke Kubota
This paper is devoted to the study of the higher index theory of codimension submanifolds originated by Gromov-Lawson and Hanke-Pape-Schick. The first main result is to constru…
Twisted crystallograpic T-duality via the Baum--Connes isomorphism
Kiyonori Gomi, Yosuke Kubota, Guo Chuan Thiang
We establish the twisted crystallographic T-duality, which is an isomorphism between Freed-Moore twisted equivariant K-groups of the position and momentum tori associated to an ext…
