On the semi-simplicity of the quantum cohomology algebras of complete intersections
Gang Tian, Geng Xu
Abstract
In this short note, we study the semi-simplicity of the quantum cohomology algebra H(V, C) of a Fano complete intersection V, and show that the subspace of H(V, C) generated by the hyperplane sections is semi-simple in the sense of Dubrovin when the degree of V satisfies certain conditions.
