Deletion of Fractional Fourier entropy

Comment: I could not find any in-depth sources that were independent of the group that developed this technique. With few publications and no in-depth secondary reliable sources, the topic fails  criteria and it seems  for this topic to be notable. Normally I'd try to find a good merge or redirect candidate, but I found nothing appropriate. Hence, delete
