Dear Hans:

	There is a very good group working in the mathematical
logic of computer science and artificial intelligence at the
University of Texas at El Paso.  I mentioned them when I was
visiting in 1987.  However, I think you are about to lose them to
other universities that are impressed by their work.  It
comprises Michael Gelfond, Teodor Przymusinski and Helena
Przymusinska.

	I don't know what the University would have to do to keep
them.
