Query: Semi-infinite A-variations of Hodge structure over extended Kahler cone   This is an expanded comment on Barannikov's paper math.AG/0006193. A
symplectic version of his construction is discussed. It is shown that the
duality transformation for mirror torus fibrations over the same Monge-Ampere
manifold exchanges semi-infinite A-variations of Hodge structure introduced in
this paper with Barannikov's semi-infinite B-variations of Hodge structure.
