Convolutions on the sphere: Commutation with differential operators
H Aluie - GEM-International Journal on Geomathematics, 2019 - Springer
We generalize the definition of convolution of vectors and tensors on the 2-sphere, and
prove that it commutes with differential operators. Moreover, vectors and tensors that are …
