 This generalizes the Weil pairing for elliptic curves.The theory was first put into a good form when "K" was the field of complex numbers.In that case there is a general form of duality between the Albanese variety of a complete variety "V", and its Picard variety; this was realised, for definitions in terms of complex tori, as soon as André Weil had given a general definition of Albanese variety.
