where Ꮿ hol .E 2i / for i D 1; 2; 3 are holomorphic Cayley transformations of the Eisenstein series E 2 , E 4 , E 6 whose expansions can be computed explicitly, while fb m;n g m;n are rational numbers that can be obtained recursively.The holomorphic anomaly equations (HAEs) discovered by Oberdieck and Pixton [42] and the Virasoro constraints discovered by Okounkov and Pandharipande [44] for the GW theory of elliptic curves also carry over to the corresponding FJRW theory. See Corollaries 23 and 24 for the explicit statements.
