The capillary $L_p$ dual Minkowski problem for $p>q$ in higher dimensions

Abstract

We prove existence and uniqueness for the capillary $L_p$ dual Minkowski problem for $p>q$ and contact angle $\theta \in (0,\frac{\pi }{2})$ in ${\mathbb{R}}^{n+1}$, $n\ge 3$. We reduce it to a Monge-Ampère type equation with a Robin boundary condition on the unit spherical cap, by building a new auxiliary function to obtain the $C^2$ estimate for $p>q$ in ${\mathbb{R}}^{n+1}$ ($n\ge 3$), we then prove that there exists a unique smooth solution that solves this problem provided $\theta \in (0,\frac{\pi }{2})$.
