While we are on the subject of the $1million questions up for grabs, has anyone seen the lecture at Clay for the Hodge conjecture? The lecturer waffles on about spaces and equivalence and doughnuts for ages, and then right at the end he is asked a question, and says that the Hodge conjecture boils down to something about skew matrices or something else. Does anyone know this - it takes ages to get to on my linear RealPlayer, and I have found no references to it elsewhere.
