Primitive Forms for Affine Cusp Polynomials    [PDF]

Yoshihisa Ishibashi, Yuuki Shiraishi, Atsushi Takahashi

We determine a primitive form for a universal unfolding of an affine cusp polynomial. Moreover, we prove that the resulting Frobenius manifold is isomorphic to the one constructed from the Gromov-Witten theory for an orbifold projective line with at most three orbifold points.
