Title: From higher-spin gauge theory to strings and tensor models
Abstract: Higher-spin gauge theory is a theory exhibiting higher symmetries
that can become manifest at ultra high (trans-Planckian) energies.
Hence, it is anticipated to be related to quantum gravity. Main
properties of nonlinear higher-spin gauge theory and underlying
structures such as unfolded formulation of dynamical equations and
noncommutative higher-spin algebra in the twisor-like spinor space
will be reviewed. The emphasize will be on the new class of models
conjectured to form holographically dual to boundary tensor models,
that are associated with Coxeter groups and Cherednik algebras.

Title: Spontaneous Symmetry Breaking in Tensor Theories
Abstract: I will talk about spontaneous symmetry breaking patterns in tensor models. The choice of patterns (into diagonal subgroups) is motivated by a natural generalization of the chiral symmetry breaking. We find the explicit form of the Goldstone bosons which are organized as matrix multiplets transforming in the adjoint of U(N) in the effective theory. This provides a neat link between tensor and matrix theories. A fact that should add to the physical meaning of tensor theories in the context of holography and quantum gravity.
