The moduli space of bilevel-6 abelian surfaces
G. K. Sankaran, J. G. Spandaw
The moduli space of abelian surfaces with polarisation of type (1,6) and a bilevel structure has positive Kodaira dimension. By contrast, Mukai has shown that the moduli space of b…

Abelian surfaces in toric 4-folds
G. K. Sankaran
We investigate the possibility of embedding minimal abelian surfaces in smooth toric 4-folds with Picard number 2. The existence of such an embedding imposes conditions on the 4-fo…

Degenerations of (1,3) abelian surfaces and Kummer surfaces
K. Hulek, I. Nieto, G. K. Sankaran
We continue our study of the geometry of Nieto's quintic threefold, looking at degenerate surfaces that correspond to certain loci and showing how they arise from a toroidal compac…
