Asymptotic Approximate Fekete Arrays

Abstract

The notion of asymptotic Fekete arrays, arrays of points in a compact set $K\subset {\mathbf{C}}^d$ which behave asymptotically like Fekete arrays, has been well-studied, albeit much more recently in dimensions $d>1$. Here we show that one can allow a more flexible definition where the points in the array need not lie in $K$. Our results, which work in the general setting of weighted pluripotential theory, rely heavily, in the multidimensional setting, on the ground-breaking work of Berman, Boucksom and Nystrom.
