abstract = {<p style="text-align: justify;">We present a fast Poisson solver on spherical shells. With a special change
of variable, the radial part of the Laplacian transforms to a constant coefficient differential
operator. As a result, the Fast Fourier Transform can be applied to solve the
Poisson equation with O(N<sup>3</sup>logN) operations. Numerical examples have confirmed
the accuracy and robustness of the new scheme.</p>},
