Localizing invariants of constructible sheaves
Qingyuan Bai, Peter J. Haine
Given an open-closed decomposition of the stratifying poset, we construct a new semi-orthogonal decomposition of the -category of constructible sheaves on a stratified spac…

On the K-theory of algebraic tori
Qingyuan Bai, Shachar Carmeli, Branko Juran +1
Given an algebraic torus over a field , its lattice of characters gives rise to a topological torus with a continuous action of the…

Toric Mirror Symmetry for Homotopy Theorists
Qingyuan Bai, Yuxuan Hu
We construct functors sending torus-equivariant quasi-coherent sheaves on toric schemes over the sphere spectrum to constructible sheaves of spectra on real vector spaces. This pro…
