Abstract

Let $\varOmega $ be an unbounded domain in a Banach space. In this work, we wish to impose local conditions on the boundary points of $\varOmega $ (including the point at infinity) that guarantee hyperbolicity and complete hyperbolicity of $\varOmega .$ We also search for local boundary conditions so that Vitali properties hold true for $\varOmega .$ These properties might be considered as analogues of the usual taut property in the finite-dimensional case.
