Todd Jay Anderson, susan koons
Author(s) of paper(s) chosen for publication: Ji Ma
Comments: any solution that was actually completed would have been chosen
for the review... Ji's solution wasnt correct, but was the closest and was
also finished, therefore, his paper was chosen...
GRADER'S COMMENTS: More specifically:
(1) The solution of the equation in z is incorrect. (Apparently he didn't
apply the right boundary conditions.)
(2) There are several mistakes in the steps leading to the formula for the
coefficients.
(3) Near the end, he implicitly used that all eigenvalues are positive but
never proved it.
