Abstract

The Π\Pi-operator (Ahlfors-Beurling transform) plays an important role in solving the Beltrami equation. In this paper we define two Π\Pi-operators on the n-sphere. The first spherical Π\Pi-operator is shown to be an L2L^2 isometry up to isomorphism. To improve this, with the help of the spectrum of the spherical Dirac operator, the second spherical Π\Pi operator is constructed as an isometric L2L^2 operator over the sphere. Some analogous properties for both Π\Pi-operators are also developed. We also study the applications of both spherical Π\Pi-operators to the solution of the spherical Beltrami equations.
