On the completeness and closure of vector and tensor spherical harmonics
2008
Integral transforms and special functions
Preserved Fulltext
An intrinsically on the 2-sphere formulated proof of the closure and completeness of spherical harmonics is given in vectorial and tensorial framework. The considerations are essentially based on vector and tensor approximation in terms of zonal vector and tensor Bernstein kernels, respectively.
