Triangle-generation in topological D-brane categories
Nils Carqueville
Tachyon condensation in topological Landau-Ginzburg models can generally be studied using methods of commutative algebra and properties of triangulated categories. The efficiency o…

IIB solutions with N>28 Killing spinors are maximally supersymmetric
U. Gran, J. Gutowski, G. Papadopoulos +1
We show that all IIB supergravity backgrounds which admit more than 28 Killing spinors are maximally supersymmetric. In particular, we find that for all N>28 backgrounds the superc…
