Early on in the development of Gromov-Witten theory, Ellingsrud and Strømme computed the number of twisted cubic curves on hypersurfaces and complete intersections of appropriate (multi-)degree. With Sabrina Pauli, we adapt their method to give a refinement to a ``count’ landing in the Grothendieck-Witt ring of quadratic forms; the rank recovers the classical count, while the signature gives...
