Dear colleagues,
It is our great pleasure to invite you to the next seminar of the “GReTA - Graph Transformation Theory and Applications” series:
Friday, June 4, 15:00 CET
“Global order routing on exchange networks”, V. Danos
(abstract, Zoom and YouTube links attached below)
The GReTA seminar series aims to serve as a platform for the international graph rewriting community, to promote recent developments and trends in the field, and to permit a regular networking and interaction between members of this community. Seminars are scheduled twice a month (cf. https://www.irif.fr/~greta/#talks<https://eur03.safelinks.protection.outlook.com/?url=https:%2F%2Fwww.irif.fr%2F~greta%2F%23talks&data=04%7C01%7Crh122%40leicester.ac.uk%7Cb6db1fe86b984040c5dc08d924084a1b%7Caebecd6a31d44b0195ce8274afe853d9%7C0%7C0%7C637580440284420311%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=8YDvV3QocK7%2FPm831%2BKpbm4vbs%2Bz0cuhwmqScTOO4xU%3D&reserved=0> for a list of upcoming events).

Title: Global Order Routing on Exchange Networks
Speaker: Vincent Danos (CNRS & Ecole Normale Supérieure, Paris, France)
Abstract:
We propose an abstract notion of networks of exchanges modelling the global money market of decentralised finance. We formalise routing and arbitrage on such networks as convex optimisation problems. We provide bounds with closed formulas in the specific case of “constant product” automated markets and a restricted form of cyclic arbitrage. We compute the associated lower bounds on actual data derived from the Ethereum blockchain. (joint work with Hamza El Khalloufi and Julien Prat)
