On July 7 we will have a seminar by

**Pietro Benetti Genolini **(King’s College London)

**Title**: Complex saddles and black holes in AdS_{4}

**Abstract**:

The large-*N* limit of the superconformal index of ABJM theory is related to black holes that are asymptotically AdS_{4}. The relation can be made more precise by mapping the index to a supersymmetric partition function on a twisted *S*^{1} x *S*^{2} background, whose large-*N* limit corresponds to the on-shell action of supersymmetric black hole solutions with appropriate boundary conditions. When computing the large-*N* limit of the partition function, we encounter a family of complex saddles labelled by an integer. In this talk, I will consider the gravitational dual of these complex saddle points.
