I will talk about the index which counts BPS local operators of the 6d (2,0) theory, calculated from gauge theories on the 5-sphere.

In this talk I discuss that non-commutative and non-associative geometry emerges for closed strings moving in non-geometric backgrounds. The origin of closed string non-commutativity (non-associativity) is due to new closed string boundary...

Almheiri, Marolf, Polchinski, and Sully have claimed that unitarity of black hole evaporation is inconsistent with the existence of a smooth horizon. I will argue that computational restrictions prevent the type of thought-experiment which...

We discuss some of the initial phenomenological successes that have been obtained by studying the recently uncovered Higgs like boson in a systematic EFT approach. We also outline how the initial steps of a systematic renormalization program has...

I'll describe a new link between supersymmetric gauge theories, with gauge group G, and the Yangian for the Lie algebra of G. The main result is that a certain twisted, deformed N=1 supersymmetric gauge theory, with gauge group G, is "controlled" by...
