Gradient Flows face-to-face 3

11 sept. 2023, 09:00 → 14 sept. 2023, 14:30 Europe/Paris

Salle Fokko-du-Cloux (Université Claude Bernard Lyon I, campus de la Doua.)

Description

This workshop is the third installment in the series "Gradient Flows face-to-face", created to once again allow researchers to meet and discuss gradient flows and related topics after the long period of homeworking and online workshops. It follows the two previous editions, held in September 2021 in Roma and in September 2022 in L'Aquila, respectively. 

The aim is to keep a working group atmosphere and encourage discussions and interactions as much as possible between participants. In order to keep the workshop at a reasonable size and allow for fruitful interactions, the number of participants is limited to approximately 50. Registrations are currently closed.

This year's workshop is fully funded by the ERC advanced grant "Everything You Always Wanted to Know About the JKO Scheme" (EYAWKAJKOS) and will be its launching event.

You can find the schedule of the conference and abstracts here. You can also find the slides of the talks at the bottom of the page or in the timetable section.
