Kahler-Ricci flow
Gang Tian
(Princeton University)
Abstract:
The Kahler-Ricci flow provides a useful method of deforming any Kahler metric towards a caononical metric. In this talk, we will discuss on recent progress on the Kahler-Ricci
flow and how the flow behaves on manifolds with positive Kodaira dimension and without Kahler-Einstein metrics.

What is the phase structure of N=4 SYM theory?
📍 London
Sean Hartnoll
(DAMTP)
Abstract:
I will review recent results at strong and weak coupling
in N=4 SYM theory at finite temperature. I will point out that retarded correlators have a qualitatively different analytic structure in the weak a strong coupling limits and will argue that this either necessitates a phase transition in the theory or requires that we revise our current understanding of weakly coupled plasmas.

Holographic decays of large-spin mesons
Marija Zamaklar
(Max Planck)
Abstract:
I will discuss the decay process of large-spin mesons in the context of the gauge-string duality, using generic properties of confining backgrounds and systems with flavour branes. In the string picture, meson decay corresponds to the quantum-mechanical process in which a string rotating on the IR wall.
fluctuates, touches a flavour brane and splits into two smaller strings. This process automatically
encodes flavour conservation as well as the Zweig rule. I will show that the decay width computed in the
string picture is in remarkable agreement with the decay width obtained using the phenomenological Lund
model.
