# ag.algebraic geometry – Descendent Gromov-Witten invariants and Frobenius manifolds

I’ve heard it said that genus $$0$$ descendent Gromov-Witten invariants of a smooth projective variety $$X$$ can be encoded in the structure of a Frobenius manifold on the cohomology $$H^*(X,mathbb{C)}$$. I am very confused by this – it is clear that this is true for non-descendent Gromov-Witten invariants. How do the descendent invariants enter in?
