摘要

This paper undertakes the construction of fractal versions of the classical sphericalharmonics. Some inequalities satisfied by the coefficients of the iterated function systems defin-ing the fractal functions provide sufficient conditions for the existence of new Hilbert bases offunctions on the sphere. This fact confirms their properties of good approximation. The method-ology used implies the definition of an operator mapping standard functions into their fractalanalogues. The transformation is linear and bounded and some upper bounds of its norm arealso established.
