A simpler kernel for stratified Mukai flops
Ed Segal, Wei Tseu
We reinvestigate the problem of describing the Fourier-Mukai kernel for the derived equivalence associated to a stratified Mukai flop. For the case of Grassmannians of planes we gi…

Window equivalences via categorical sl(2) actions
Wei Tseu
We identify two distinct approaches to the derived equivalence for the stratified Mukai flop of cotangent bundles of Grassmannians -- one induced by the geometric categorical sl(2)…
