John Pardon has recently proved the Gromov-Witten Donaldson-Thomas correspondence using a new homology/cohomology machinery for 1-cycles in 3-folds. We study a much simplified version, namely for 0-cycles (points) in curves. In this case the theory is quite simple to explain, but still exhibits some interesting features of Pardon’s theory.
