Quadrality for Supersymmetric Matrix Models

Sebastian Franco, Sangmin Lee, Rak-Kyeong Seong +1

We introduce a new duality for supersymmetric gauged matrix models. This duality is an order 4 symmetry, namely an equivalence between four different theories,…

Super-Laplacians and their symmetries

P. S. Howe, U. Lindström

A super-Laplacian is a set of differential operators in superspace whose highest-dimensional component is given by the spacetime Laplacian. Symmetries of super-Laplacians are given…

The fate of stringy AdS vacua and the WGC

Ulf Danielsson, Giuseppe Dibitetto

The authors of arXiv:1610.01533 have recently proposed a stronger version of the weak gravity conjecture (WGC), based on which they concluded that all those non-supersymmetric AdS…
