The Pan-STARRS1 $z > 5.6$ Quasar Survey: III. The $z \approx 6$ Quasar Luminosity Function

Jan-Torge Schindler, Eduardo Bañados, Thomas Connor +9

We present the $z \approx 6$ type-1 quasar luminosity function (QLF) based on the Pan-STARRS1 (PS1) quasar survey. The PS1 sample includes 125 quasars at $z \approx 5.7 - 6.2$ with $…

Existence of harmonic maps and eigenvalue optimization in higher dimensions

Mikhail Karpukhin, Daniel Stern

We prove the existence of nonconstant harmonic maps of optimal regularity from an arbitrary closed manifold $(M^{n}, g)$ of dimension $n > 2$ to any closed, non-aspherical manifold $N$ …

Quantization and non-quantization of energy for higher-dimensional Ginzburg-Landau vortices

Alessandro Pigati, Daniel Stern

Given a family of critical points $u_{ε} : M^{n} \to C$ for the complex Ginzburg--Landau energies \begin{align*} &E_ε(u)=\int_{M}\left(\frac{|du|^2}{2}+\frac{(1-|u|^2)^2}{4ε^2}\ri…
