The noncommutative divisor deformation conjecture for the fibrewise compactification

Let \EuScriptA\EuScript A be the Fukaya AA_\infty-algebra of the Lefschetz fibration and \EuScriptBq,bˉM\EuScript B_{q,\bar b|M} the category associated to the fibrewise compactification. Suppose that the deformation \EuScriptAq,bˉ\EuScript A_{q,\bar b} is trivial. Noncommutative divisor deformation conjecture. The category \EuScriptBq,bˉM\EuScript B_{q,\bar b|M} has the structure of a deformation of noncommutative divisors on \EuScriptA\EuScript A, whose leading-order term is the image of the deformation of the canonical natural transformation under the trivialization isomorphism. This conjecture extends the noncommutative-divisor structure established for the undeformed fibre category to fibrewise compactifications.
