Index theory and noncommutative geometry of topological insulator [PDF]

arXiv, 2018
In this chapter, we report the recent progress in the understanding of the rich mathematical structures of topological insulators in the framework of index theory and noncommutative geometry.

Topological Homotopy Groups [PDF]

Bulletin of the Belgian Mathematical Society, 15:3 (2008) 588-600, 2011
D. K. Biss (Topology and its Applications 124 (2002) 355-371) introduced the topological fundamental group and presented some interesting basic properties of the notion. In this article we intend to extend the above notion to homotopy groups and try to prove some similar basic properties of the topological homotopy groups.

Negative dimension in general and asymptotic topology [PDF]

arXiv, 2006
We introduce the notion of negative topological dimension and the notion of weight for the asymptotic topological dimension. Quantizing of spaces of negative dimension is applied to linguistic statistics.

Nonperturbative refined topological string [PDF]

arXiv
A formula for the full nonperturbative topological string free energy was recently proposed by Hattab and Palti \cite{HP24a}. In this work, we extend their result to the refined topological string theory. We demonstrate that the proposed formula for the full nonperturbative refined topological string free energy correctly reproduces the trans-series ...
