Calabi-Yau three-folds and moduli of abelian surfaces II
We give explicit descriptions of the moduli spaces of abelian surfaces with polarizations of type $(1,d)$, for $d=12,14,16,18$ and $20$. More precisely, in each case we show that a certain choice of moduli space of such abelian surfaces with a partial level structure can be described explicitly and is unirational, …
