General type results for moduli of deformation generalised Kummer varieties

Abstract

In arXiv:1710.01672, we obtained general type results for orthogonal modular varieties associated with moduli spaces of compact hyperkähler manifolds of deformation generalised Kummer type (also known as 'deformation generalised Kummer varieties'). The orthogonal modular varieties were defined in terms of an integer 2d, corresponding to the degree of polarisation of the associated hyperkähler manifolds. In arXiv:1710.01672, we showed these orthogonal modular varieties are of general type when 2d is square-free and sufficiently large. Here we show that the square-free condition can be removed.
