Dear Colleague,

Given the continuous global health threat posed by the COVID-19 pandemic, in November, 2020 we decided to postpone the 32^nd International Symposium on Rarefied Gas Dynamics (RGD32) to the summer of 2022.

To continue engagement in the RGD community and bring together researchers, especially graduate students, RGD32-LOC along with the International Advisory Committee (IAC) will hold the pre-RGD32 workshop on recent hot topics in RGD online (no registration fee; Zoom-platform; unlimited participants).

The dates for the Pre-RGD32 online workshop are July 7th-9th (Wed-Fri; 3.5 hours each day), 2021 in GMT calendar. (Tentative times are July 7^th Wed 13:00-16:30, 8^th Thu 13:00-16:30, 9^th Fri 23:00-02:30 in GMT-London.)

This 3-day (10.5 hours in total) workshop will cover several real-time invited lectures and real-time (10 mins) Q&A sessions for pre-recorded (20~30 mins) contributed presentations (with no proceeding publication).

We cordially invite you to participate in this virtual Pre-RGD32 workshop.

Presenters are invited to submit their one-page abstracts before May 10th, 2021 by email at prergd32@gnu.ac.kr (primary) or prergd32nd@gmail.com (backup).

Abstract template (attached to the present email) and further information are available at http://www.rgd32.org/preworkshop.asp. (Book of abstracts will be available from June 1^st, 2021.)

We look forward to meeting you at the virtual workshop on July 7th-9th, 2021.

Sincerely,
