Workshop Summary

by John Tomsick, Sylvain Guiriec, and Henric Krawczynski

We had a productive workshop at Clemson University on October 1st, with about a dozen people attending in person and several more on the WebEx.

We made significant progress on the GammaSIG White Papers. We decided on the focus of each of the 5 WPs, discussed their content, assigned leaders to each one, and spent time writing.

You can see where we are on the 5 WPs by looking at the information below. Links are either to Overleaf or Google docs. If you have any problems accessing the Google docs, please click on the "Request access" button.

Our internal deadline for having readable drafts is November 9th, but input is welcome before then. In fact, WP#2 is already quite advanced. Input can be given by e-mailing one of the GammaSIG leaders (Sylvain/John/Henric) or the individual WP leaders (see below).

Finally, thanks very much to Dieter Hartmann for hosting the workshop.
