| Abstract | |
We supply a Fourier characterization for the real, continuous, isotropic and strictly positive definite kernels on a product of circles. In other words, if is the unit circle in , is the usual inner product of and f is a real continuous function on , we determine necessary and sufficient conditions in order that be a strictly positive definite kernel on .
