Boundary smoothness conditions for analytic Lipschitz functions (2501.19181v1)

Abstract: For an open set $U \subseteq \mathbb C$ and $0 < \alpha < 1$ we define $A_\alpha(U)$ to be the set of functions in the little Lipschitz class that are analytic in a neighborhood of $U$. We consider three conditions that show how the functions in $A_\alpha(U)$ can be smoother at a boundary point than would otherwise be expected. We prove an implication between conditions $(c)$ and $(b)$ and show that there is no implication between conditions $(a)$ and $(c)$.
