We shall discuss the chiral algebras of a (0,2) sigma-model on homogeneous flag manifolds of various dimensions. As is by now well-known, the chiral algebras can be described by the theory of "Chiral Differential Operators" within perturbation...

We will consider stability in the string theory landscape. A survey over several classes of flux vacua with different characteristics indicates that the vast majority of flux vacua with small cosmological constant are unstable to rapid decay to a...

Non-abelian maximally supersymmetric Yang-Mills theory on a flat spatial three-torus has an intricate structure of normalizable zero-energy states, characterized by their values of the discrete abelian electric and magnetic 't Hooft fluxes, and by...
