From modular graph forms to iterated integrals (Part 2)

Emil Claasen (MPI, Potsdam)

Abstract: Modular Graph Forms (MGFs) are a class of modular forms represented by lattice sums associated to directed simple graphs. They originated from the calculation of graviton amplitudes in type...

Renormalising Non-Commutative Singular PDEs

Martin Peev (Inperial College, London) (online)

When attempting to construct QFTs that include Fermions using the methods of Stochastic Quantisation, one is naturally forced to consider noncommutative stochastic PDEs. I shall show how to formulate...

Matched pairs, post-Hopf algebras and the quantum Yang-Baxter equation

Yunan Li (Guangzhong, China) (online)

Recently, Ferri and Sciandra introduced two equivalent notions, matched pair of actions on a Hopf algebra and Yetter-Drinfeld brace. Any of these objects actually provides a solution of the quantum...
