Subject Re: [math] Matrix subMatrix and mean methods
Date Thu, 07 Oct 2004 04:01:04 GMT
Hi Brian,

After being reminded by Wolfgang that he had previously given me a 
contact at CERN to discuss these issues with, I emailed that contact. He 
forwarded me to the Technology Transfer officer for CERN. I just 
finished emailing a request to that individual to comment on the 
position CERN holds on this subject of relicensing/donation. Once we 
hear back from them we can also include this information into the 
discussion. I expect it will clarify if any opposition does exist at the 
original institution.
