We prove a Fatou-type theorem and its converse for certain positive eigenfunctions of the Laplace–Beltrami operator L on a Harmonic NA group. We show that a positive …
The Generalization of Fatou’s Theorem and Its Converse The Generalization of Fatou’s Theorem and Its Converse Abstract We consider a function K(x) on ℝ n which satisfies certain …
A classical result due to Fatou relates the radial and nontangential behaviour of the Poisson integral of suitable measures on the real line with certain differentiability properties of the …
