Let $X$ be a Calabi–Yau manifold. Write $X^{op}$ for a second copy of $X$ with the symplectic structure reversed, and let the diagonal brane be the diagonal submanifold…

Let $X$ be a Calabi–Yau manifold, and consider its category of A-branes, namely the derived category of the Fukaya category. The diagonal brane is the diagonal submanifold…

Equivariant reduction conjecture. The theory computes the $A$-model correlator of the reduced symplectic manifold $\mu^{-1}(0)/G$.

Let $\mathbb{R}^2\times\mathbb{C}^4$ carry the product geometry, and consider the $SU(4)$-invariant twist of type IIA superstring theory. Type IIA string twist conjecture. The twis…
