What is Poles, Zeros, and Sheaf Cohomology about?
The Fundamental Pole-Zero Exact Sequence for a transfer function matrix, first enunciated in 1989, supplies a structural meaning to the hope that "the number of zeros of a transfer function is the same as the number of poles". This principle requires the inclusion of generic zeros counted using Wedderburn-Forney spaces which measure the kernel and cokernel of the transfer function. In this brief note we identify the Wedderburn-Forney space as a cohomology group and give a new approach to the Fundamental Pole-Zero Exact Sequence in terms of exact sequences of sheaf cohomology groups.
