Let $n$ be a positive integer and let $V\subseteq\mathbb{A}_{\mathbb{C}}^{n}$ be an algebraic variety. For a subvariety $X\subseteq V$, define its defect by … The subvariety $X$ is…

Let $K$ be the number field, ${\cal P}$ a prime ideal in its ring of integers, and let $\gamma {\Bbb B}_d$ be a polyhedron in the Bianchi decomposition of the orbifold…

Let $M_{A,2d}$ be the modular variety associated with the lattice and polarisation considered in the source, with $d=2^n$. Non-general-type conjecture. The variety $M_{A,2d}$ is no…

The theorem identifies three modular varieties of Kodaira dimension zero, namely the varieties among $\mathcal S\mathcal M(D_n)$ and the two additional varieties stated there. Cala…
