A Uniqueness Theorem for Frobenius Manifolds and Gromov--Witten Theory   for Orbifold Projective Lines
  We prove that the Frobenius structure constructed from the Gromov-Witten theory for an orbifold projective line with at most three orbifold points is uniquely determined by the WDVV equations with certain natural initial conditions.
