The cohomology of framed moduli spaces and the coordinate ring of torus fixed points of quotient singularities

Kohei Hatano

If two conical symplectic resolutions $X\to X_0$ and $X^{!}\to X_0^{!}$ are symplectic dual, the cohomology ring $H^{\ast }(X)$ and the coordinate ring of ${\mathbb{C}}^{\ast }$-fixed points in $X_0…
