I have a small problem, recently I have asked a question about Cassel's statement and after waiting for many days, I have decided to keep a bounty. And atlast one day I have received a considerably good answer from Prof.Franz Lemmermeyer. His answer served in providing a beautiful reference.
But its after much strenuous efforts, at-last I got a photo-copy of the Appendix-B. It in-fact contains a brief summary about Tamagawa Numbers, but it didn't give a clear description about the exact point I was asking for ( I mean how can tamagawa numbers, serve as a modern-reformulation of Local-Global Principle for genus-0 curves in terms of quantitative measure ) .
So I am saying that there might be a clear information present in that paper, but it is not complete in this context. Is there any way that some one just post a brief gist about my question ? . I think even a whole topic can be given a brief description. I mean one can paraphrase the entire complex thing into a paragraph in a elegant manner just giving some description.
Like there was a fantastic attempt done by Prof.Matthew Emerton in answering a similar question regarding a reference here . He has posted a very long and an elegant explanation. But I think not all times I can expect such a beautiful answer. And that too now-a-days Prof.Emerton, seems to be so busy in his work, so its not fair to again start a meta topic.
So main purpose of opening this meta topic is that , Can I again keep a bounty for the same question asking to give a clear reference. I wanted to ask this at the comments section present at the question, but later I understood that its not fair on my part to disturb a good mathematician like Prof.Franz Lemmermeyer to answer my question leaving all his work. ( In that case I mustn't have disturbed another seminal mathematician like Prof.Emerton , but I am having a small hope , a small confidence that he might answer one day or the other ) . So I am making this attempt.
So Please answer me one thing, Is there any way to again keep a bounty for a question, which already had a bounty ?
