The company is associated with Earl Grey tea, a tea infused with bergamot, though it is unclear when this association began, and how important the company's involvement with the tea has been; Jacksons of Piccadilly, originally a rival of Twinings, but bought up by Twinings in the 1990s, also have associations with
Dual abelian variety soon as André Weil had given a general definition of Albanese variety. For an abelian variety "A", the Albanese variety is "A" itself, so the dual should be "Pic"("A"), the connected component of what in contemporary terminology is the Picard scheme. For the case of the Jacobian variety "J" of a compact Riemann surface "C", the choice of a principal polarization of "J" gives rise to an identification of "J" with its own Picard variety. This in a sense is just a consequence of Abel's theorem. For general abelian varieties, still over the complex numbers, "A" is in the same
