review text: Summary: The leading term of a convolution of quasipolynomials with periods \(p\) and \(q\) is periodic with period \(\gcd(p,q)\), smaller than expected. The degree of the convolution is usually \(d+e+1\); we characterize the exceptions. To do this we need to characterize the null space of a circulant matrix.
