Let a stack with a torus action be equipped with a perfect obstruction theory, and let its fixed substack carry the modified perfect obstruction theory compatible with that of the…

Higher-genus correction-term conjecture. In higher genera, there are natural correction terms that cancel the negative powers of the weight $E|_{P_i}$, and the resulting modified v…

Modified localization conjecture. An analog of the theorem asserting that modified virtual localization computes the genus-one Gromov–Witten invariants of a Calabi–Yau hypersurface…

Let $X$ be an equivariant virtually smooth scheme with fixed-point components $X_i$, inclusion $\iota:\bigcup X_i\to X$, virtual structure sheaves…
