With this weekly Webinar, our goal is to contribute an initiative to foster the communication of PDE- related research during these trying times. Just as the journal of the same name, the SN PDEA Webinar is aiming to bridge the areas of Mathematical Analysis, Computational Mathematics and applications of Mathematics in the Sciences. The first three presentations will be given by Huyen Pham (Universite Paris Diderot), Eitan Tadmor (University of Maryland), and Diogo Gomes (KAUST). Starting on February 8, Webinars will take place on Mondays on a weekly basis at 9am EST, 3pm CET. They will be held via Zoom and will be free to attend. Registration for the webinar series is now open at (if you already registered last year, your old personalised Zoom link will continue to work) https://springer.zoom.us/meeting/register/tJ0uf-iopzkvGdJJpq42h5f7wOqUcKtCc7y7 More information and updates on the Webinar can be found at https://www.springer.com/journal/42985/updates/18235540 and video recordings of last year's talks can be found here https://www.youtube.com/playlist?list=PLhvxnk1Oo_8hl6Rf8ECbE4FssnfmbZHwK ------------------------------------------------------- From: Suzanne Shontz [log in to unmask] Date: January 25, 2021 Subject: Deadline extended, PDSEC, ONLINE, May 2021 The paper submission deadline for the 22nd IEEE international Workshop on Parallel and Distributed Scientific and Engineering Computing (PDSEC-21) (http://www.ieee-tcsc.org/2021/pdsec/) has been extended to February 5, 2021.
