Fatou's Theorem and minimal graphs

AbstractIn this paper we extend a recent result of Collin–Rosenberg (a solution to the minimal surface equation in the Euclidean disc has radial limits almost everywhere) to a large class of differential operators in Divergence form. Moreover, we construct an example (in the spirit of Collin and Rosenberg [2]) of a minimal graph in M2×R, where M2 is a Hadamard surface, over a geodesic disc which has finite radial limits in a measure zero set
