i recently heard that there was a conference on Birch and Swinnerton dyer conjecture Held at Cambridge on May 4 until May 6, the main theme is "The conference marks the 50th anniversary of the Birch-Swinnerton-Dyer Conjecture and aims both to explain the state of our knowledge and to reflect on the modern approaches to the conjecture and related problems."
but unfortunately i cant find any video archives about the conference in any of the google searches ,but i found some pdf files,and photos which are not informative in the conference site of MR.Tim Dokchitser,
so can anyone give a reference to the video archive site of that conference ,or does the video archive exists???
i forward this question to Mr.William Stein,and Tim dokchitser,who were the key persons in organizing ,if they are successful in giving me the appropriate links of video archive i would be much thankful
thanks a lot everyone,touch your feet for your help
