A new class of higher-spin gauge theories associated with various Coxeter groups is proposed. The emphasize is on the Bp--models. The multi-particle B2--higher-spin theory is conjectured to be associated with String Theory. Bp--higher-spin models...

I will make some preliminary investigations to perturbativedynamics in AdS, more precisely the Mellin amplitudes associated to particle scattering, at loop level. With a focus on scalar effective theories, this analysis is fulfilled by introducing...

We discuss some target space aspects of the FZZ duality both in the Euclidean setup of the cigar geometry and in the SL(2)/U(1) black hole. We argue that the 2D classical SL(2)/U(1) black hole could shed some light on quantum black holes in higher...

Borcherds Kac-Moody (BKM) algebras are a generalization of familiar Kac-Moody algebras with imaginary simple roots. On the one hand, they were invented by Borcherds in his proof of the monstrous moonshine conjectures and have many interesting...

Eigenstate thermalization hypothesis (ETH) is a phenomena often observed in systems characterized by quantum chaos. In this talk, we study ETH in 2d CFTs with large central charges. In particular, we focus on observables consisting of bilocal "probe...

In my talk I will explicitly describe what topological termspreserving time-reversal symmetry one can introduce in 3+1d Yang-Mills theory. Classification of such terms corresponds to classification of SPTs via cobordisms proposed by Kapustin and...

In this talk I review new results obtained for SCFT's in 4 and 5 dimensions by compactifying 6 dimensional (1,0) SCFT's on a circle or on Riemann surfaces.

After recalling how some 4d N=2 gauge theories arise from reductions of 6d N=(2,0) superconformal theories on a Riemann surface, I will discuss two discrete quotients with codimension 2 orbifold singularities. In the first case the orbifold acts by...
