The Singularity of Kontsevich's Solution for $QH^{*}(CP^2)$
Abstract
Description
We study the singularity of the Kontsevich's solution of the WDVV equations of associativity. We prove that it corresponds to a singularity in the change of two coordinates systems of the Frobenius manifold given by the quantum cohomology of $CP^2$.
