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

RESUMO

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 $\mathbb{R}^{n+1}$, $n\geq 3$. 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 $\mathbb{R}^{n+1}$ ($n\geq 3$), we then prove that there exists a unique smooth solution that solves this problem provided $\theta\in (0, \frac{\pi}{2})$.
