1D Landau-Ginzburg Superpotential of Big Quantum Cohomology of ℂℙ²

Using the inverse period map of the Gauss-Manin connection associated with *(ℂℙ²) and the Dubrovin construction of Landau-Ginzburg superpotential for Dubrovin-Frobenius manifolds, we construct a one-dimensional Landau-Ginzburg superpotential for the quantum cohomology of ℂℙ². In the case of small qu...

Zusammenfassung:Using the inverse period map of the Gauss-Manin connection associated with *(ℂℙ²) and the Dubrovin construction of Landau-Ginzburg superpotential for Dubrovin-Frobenius manifolds, we construct a one-dimensional Landau-Ginzburg superpotential for the quantum cohomology of ℂℙ². In the case of small quantum cohomology, the Landau-Ginzburg superpotential is expressed in terms of the cubic root of the -invariant function. For big quantum cohomology, the one-dimensional Landau-Ginzburg superpotential is given by Taylor series expansions whose coefficients are expressed in terms of quasi-modular forms. Furthermore, we express the Landau-Ginzburg superpotential for both small and big quantum cohomology of *(ℂℙ²) in closed form as the composition of the Weierstrass ℘-function and the universal coverings of ℂ∖(ℤ⊕eπⁱᐟ³ℤ) and ℂ∖(ℤ⊕ℤ), respectively.
