Dear All, After over a half year the so called “updating and transition” of the University of Memphis IT system, eventually we do not have any server to host personal website for faculty (except a blog type website which is extremely inconvenient). So I decided to transfer the URL of the Banach Space Bulletin board to the following address using a free service: https://bentuo.wixsite.com/banach To avoid flooding everybody’s email box with too many announcements for the past half a year, I will let you check the link of the most recent preprints by yourself. Best regards, Bentuo Zheng
