Query: Frobenius manifold structures on the spaces of abelian integrals   Frobenius manifold structures on the spaces of abelian integrals were
constructed by I. Krichever. We use D-modules, deformation theory, and
homological algebra to give a coordinate-free description of these structures.
It turns out that the tangent sheaf multiplication has a cohomological origin,
while the Levi-Civita connection is related to 1-dimensional isomonodromic
deformations.
