Towards a general formulation of the AdS/RF correspondence
“The AdS/Ricciflat correspondence links families of asymptotically AdS spacetimes to families of asymptotically flat spacetimes. In its original formulation, this map requires a high degree of symmetry, limiting its possible applications. I will show how to relax these restrictions for linearized perturbations around solutions connected via the original AdS/RF correspondence. This should allow us to develop a detailed holographic dictionary for asymptotically flat spacetimes.”

Ftheory and
“I will discuss supersymmetric solutions in Ftheory, that is Type IIB supergravity with varying axiodilaton, which are holographically dual to 2d superconformal field theories with small superconformal algebra. The aim of this work is to set up holography in the context of Ftheory, which are traditionally two distinct areas of string theory. The talk will be based on the arXiv paper 1705.04679.”

Supergravity duals to fivedimensional supersymmetric gauge theories
“We start from field theories defined on squashed fivespheres with symmetry. The gravity duals are constructed in Euclidean Romans gauged supergravity in six dimensions. We compute the renormalized onshell actions for the solutions. The results agree perfectly with the large limit of the dual gauge theory partition function, which we compute using large matrix model techniques. We conjecture a general formula for the partition function on any fivesphere background, which for fixed gauge theory depends only on a certain supersymmetric Killing vector. We then proceed to study Euclidean Romans supergravity in six dimensions with a nontrivial Abelian Rsymmetry gauge field. We show that supersymmetric solutions are in onetoone correspondence with solutions to a set of differential constraints on an structure. We then see applications for these results.”

The moduli space of heterotic systems
“A heterotic system is a quadrupole where is a seven dimensional manifold with an integrable structure , is a bundle on with an instanton connection , is the tangent bundle with an instanton connection and is a three form on determined uniquely by the structure on . Further, is constrained so that it satisfies a condition that involves the ChernSimons forms of and , thus mixing the geometry of with that of the bundles (this is the so called anomaly cancellation condition). In this talk I will describe the tangent space of the moduli space of these systems. We first prove that a heterotic system is equivalent to an exterior covariant derivative on the bundle which satisfies for some appropriately defined projection of the operator . Remarkably, this equivalence implies the (Bianchi identity of) the anomaly cancellation condition. We show that the infinitesimal moduli space is given by the cohomology group and therefore it is finite dimensional. Our analysis leads to results that are of relevance to all orders in . Time permitting, I will comment on work in progress about the finite deformations of heterotic systems and the relation to differential graded Lie algebras.”
