Witten diagrams and the geometry of conformal blocks
Eliot Hijano (UCLA)
In this talk I will discuss the relation between conformal blocks and anti-de Sitter gravity (AdS) through the AdS/CFT correspondence. I will describe a new method for decomposing Witten diagrams into conformal blocks, and introduce geodesic Witten diagrams which provide an intuitive geometric bulk description of a conformal block. I will also present a unified framework for the holographic computation of Virasoro conformal blocks at large central charge.
