I've since come across a couple more references (items [6] and [10]
below, by accident) and I thought it would be useful to archive all
the references together in a sci.math post. I'm beginning a new
thread because google's "statue of limitations" for replying to
a post has expired for my earlier post.
The references below are ordered by publication date.
