Let $X\to\mathbb P^n$ be an abelian fibration, let $P\to\mathbb P^n$ be its relative Picard, and let $X_0$ be the relative Picard of $P$. Let…

Let $X^{2n}$ be an irreducible holomorphic symplectic manifold equipped with an abelian fibration whose fibres have polarization type $(1,\ldots,1,n+1)$. Assume the fibration admit…

Let $X^{2n}$ be an irreducible holomorphic symplectic manifold equipped with an abelian fibration whose fibres are isomorphic to Jacobians of curves. A multisection is a subvariety…

Let $X$ be an irreducible holomorphic symplectic manifold, and let $q_X$ denote its Beauville–Bogomolov quadratic form. A divisor is nef if it has nonnegative intersection with eve…

Gross–Pavanelli's mirror conjecture. The mirror of $X$ is $\check{X}$, and the mirror of $\check{X}$ is $Y$.

Let $X$ be a projective manifold such that the cotangent bundle $\Omega_X$ is pseudoeffective. Assume that $X$ admits an abelian fibration $f:X\to C$ onto a curve $C$, and let $F$…
