Title: An Introduction to Causal Set Theory Speaker: Dionigi M.T. Benincasa (DIAS) Abstract: Causal set theory is a sum-over-histories approach to quantum gravity, where the histories are discrete spacetimes (called causal sets) defined as locally finite partial orders. Causal sets were… Read More

Title: A Hopf algebra for Feynman diagrams and integral Speaker: Ruth Britto (Trinity College Dublin) Abstract: I will present a combinatorial operation on one-loop Feynman diagrams, described by cutting and pinching edges, that corresponds to the Hopf-algebraic coaction on the… Read More

Title: An M5-Brane Model Speaker: Christian Sämann (Heriot-Watt University) Abstract: We show how to write an action for a classical six-dimensional superconfomal field theory containing a non-abelian tensor multiplet. All of the ingredients of this action have been available in… Read More

Title: Commuting Matrices, MacDonald Identities & Supersymmetric Gauge Theory Speaker: Giovanni Felder (ETH Zurich) Abstract: I will introduce the notion of representation homology, following Berest, Khatchatrian and Ramadoss, and discuss some examples, applications and open problems about pairs of commuting… Read More

Title: Quantum Aspects of Black Hole and Fuzzy Sphere in String Theory Speaker: Yoshifumi Hyakutake (Ibaraki University, Japan) Abstract: One of important directions in superstring theory is to reveal quantum nature of black hole. In this talk we embed Schwarzschild… Read More

Title: Top Mass from Asymptotic Safety Speaker: Astrid Eichhorn (University of Heidelberg) Abstract: I will introduce the key ideas underlying the asymptotic safety scenario, which is mainly explored as a model of quantum gravity and will review its current status. I… Read More

Title: Towards understanding the endpoint of the superradiant instability: Kerr black holes with synchronised hair Speaker: Eugen Radu (Aveiro University) Abstract: A 50 year-old lingering question in black hole (BH) physics is the endpoint of the Kerr BH superradiant instability, triggered… Read More
