Author(s) of paper(s) chosen for publication:  [Robinson and Zhang]
                          
Comments: Two of the three papers had correct proofs that were easy to
follow.  The third paper seemed like it needed just a couple more lines
until it was finished.  The published paper was chosen on it's attention
to detail and good organization.
         
INSTRUCTOR'S COMMENT:  None of the papers was entirely adequate, but
Robinson and Zhang are close.  Nobody understood the hint, which called
for considering TWO vector fields, related by the 90-degree-rotation
operator defined on p. 341 (which is in Sec. 7.2, not 6.2 -- that's a typo
in the book).  This problem is essentially the same as Worked Problem 4 in
Chapter 6 of the Schaum's Outline book.
