This is probably a really old version of this. Modern notebook directories look like sage_notebook.sagenb
. May we ask what the lectures are? It's possible there is an updated version. In any case, if you upload the worksheet (.sws
) files as Dirk explains, this directory will be recreated in your own .sage
directory (usually located in your $HOME
directory).
Edit: In personal correspondence, you verified that this is from http://modular.math.washington.edu/ed... from the website
http://modular.math.washington.edu/ed...; this is indeed from an archaic version of Sage. You could conceivably compress each of the directories in the directory worksheets
into a .bz2 file and then rename it as .sws
and try to upload it, but I suspect that won't work, given that the internals are different.
In this particular case, I would write a script to look at the directory pub
and extract the worksheet.txt
file in each folder in there to be uploaded to your Sage notebook; it's not perfect but I just tried it and they do work, though it looks like some of them may be incomplete in various ways. In truth, you may want to see if there is a more recent version of some of William's stuff on the BSD conjecture, which there likely is! Good luck.
