Ahlfors reflection theorem for $p$ -morphisms

Pekka Koskela, Pekka Pankka, Yi Ru-Ya Zhang

We prove an Ahlfors refection theorem for $p$ -reflections over Jordan curves bounding subhyperbolic domains in $C^$ .

Strong stability for the Wulff inequality with a crystalline norm

Alessio Figalli, Yi Ru-Ya Zhang

Let $K$ be a convex polyhedron and $F$ its Wulff energy, and let $C (K)$ denote the set of convex polyhedra close to $K$ whose faces are parallel to those of $K$ .…

Second order regularity for elliptic and parabolic equations involving $p$ -Laplacian via a fundamental inequality

Hongjie Dong, Peng Fa, Yi Ru-Ya Zhang +1

Denote by $Δ$ the Laplacian and by $Δ_{\infty}$ the $\infty$ -Laplacian. A fundamental inequality is proved for the algebraic structure of $Δ v Δ_{\infty} v$ : for every $v \in C^{\infty}$ ,…

C^1-Regularity of planar \infty-harmonic functions - REVISIT

Yi Ru-Ya Zhang, Yuan Zhou

In the seminal paper [Arch. Ration. Mech. Anal. 176 (2005), 351--361], Savin proved the $C^{1}$ -regularity of planar $\infty$ -harmonic functions $u$ . Here we give a new understanding…
