Abstract

In this paper, we explore the geometric properties of unbounded extremal domains for the p-Laplacian operator in both Euclidean and hyperbolic spaces. Assuming that the nonlinearity grows at least as the nonlinearity of the eigenvalue problem, we prove that these domains exhibit remarkable geometric properties and cannot be arbitrarily wide. In two dimensions, we prove that such domains with connected complements must necessarily be balls. In the hyperbolic space, we highlight the constraints on extremal domains and the geometry of their asymptotic boundaries.
