Abstract:We study the geography problem for 3-folds of general type through the asymptotic behavior of invariants of $n$-th root covers. We first prove, in arbitrary dimension and for non-singular branch loci, that the Chern numbers are asymptotic to $n$ times the corresponding logarithmic Chern numbers of the base pair. In dimension three, for simple normal crossing branch divisors, we construct cyclic partial resolutions using toric methods and prove that, for asymptotic arrangements, the invariants $c_1^3, c_1c_2$, and $c_3$ have the same asymptotic behavior. We also obtain explicit families of 3-folds with ample canonical divisors that exhibit controlled Chern slopes.
