Abstract: For the complete intersections in projective spaces, we use the monodromy action and the classical invariant theory to study the WDVV equation. We will discuss to what extent the big quantum cohomology involving primitive classes can be determined. If time permits we will relate our result to the work of Clemens and Griffiths on the Fano variety of lines.
