On the 1st of May 2021, as part of the English-speaking seminar of NLS-Quebec, Yves Vanderveken gave a conference under the title: Satisfaction. The introduction was made by Ruzanna Hakobyan. Oriented towards the 2021 NLS Congress, this conference also resonates with the 2022 NLS Congress, because it addresses the issue of repetition and fixation through the drive.
