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…

Fundamental group of locally symmetric varieties

G. K. Sankaran

Take a bounded symmetric domain $D$ and an arithmetic subgroup $Γ$ of $Aut (D)$ . Take the quotient $D /Γ$ , compactify and resolve the singularities. We study the fundamental gr…

Moduli of abelian surfaces with a $(1, p^{2})$ polarisation

v. A. Gritsenko, G. K. Sankaran

We show that the (compactified) moduli space of abelian surfaces with a polarisation of type $(1, p^{2})$ is of general type for $p \geq 11$ , improving a result of O'Grady.

The Fundamental Group of Some Siegel Modular Threefolds

K. Hulek, G. K. Sankaran

Let A be the moduli space of (1,p)-polarised abelian surfaces with a level structure, for p an odd prime. Let X be a desingularisation of any algebraic compactification of A. Then…
