I just wonder about Kapranov's <a href="http://books.google.de/books?id=TOPa9irmsGsC&pg=PA119&lpg=PA119&dq=Kapranov+%22%22Analogies+between+Langlands+Correspondence+and+topological+quantum+field+theory%22%22&source=bl&ots=kGZ-Wnk_Fu&sig=G-E6CK1Rza5dfp2niaBOmIdoN0w&hl=de&ei=bSQJS7WAMZaInQPV45jACg&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBAQ6AEwAA#v=onepage&q=Kapranov%20%22%22Analogies%20between%20Langlands%20Correspondence%20and%20topological%20quantum%20field%20theory%22%22&f=false" title="google books">"Analogies between Langlands Correspondence and topological QFT"</a>. I would like to read a more detailed exposition and how one turns that analogy into concrete conjectures. Exist texts from courses or seminars on that? Has <a href="http://www.worldscibooks.com/mathematics/7164.html" title="book anouncement">this book</a> by İkeda already been published and reviewed?
