Abstract
We present a necessary and sufficient condition for the singularity of
circulant matrices associated with directed weighted cycles. This
condition is simple and independent of the order of matrices from a
complexity point of view. We give explicit and simple formulas for the
Drazin inverse of these circulant matrices. We also provide a
Bjerhammar-type condition for the Drazin inverse.
