An Archimedean height pairing on the equivalence relation defining Bloch's higher Chow groups
The existence of a height pairing on the equivalence relation defining Bloch's higher Chow groups is a surprising consequence of some recent joint work by myself and Xi Chen on a nontrivial -class on a self-product of a general surface. I will explain how this pairing comes about.
