The GW effective-algorithm conjecture for quintic threefolds
The GW effective-algorithm conjecture for quintic threefolds
Let be the genus , degree Gromov–Witten invariant of the quintic threefold, and let be the genus FJRW invariant of the Fermat quintic with many -insertions. Let and be positive integers, and let the relations be those obtained from the localization vanishing.
GW effective-algorithm conjecture. By choosing and positive, these relations provide an effective algorithm to determine all genus GW invariants , provided that
and
This strengthens the preceding effective algorithm by asserting that suitable positive choices of the two degrees remove the need for same-genus lower-degree GW initial values.
