The local supersymmetries of a stack of branes
Raphaël Dulac, Yixuan Li
Local supersymmetries have been a guiding principle to construct smooth horizonless supergravity solutions. By computing brane densities from the brane low-energy effective action,…

The 1/4-BPS building blocks of brane interactions
Ben Eckardt, Yixuan Li
We study, from the perspective of supersymmetry and space-time Killing spinors, the local brane densities involved in 1/4-BPS intersecting brane systems. In particular, we classify…
