Let L p u = d 4 u/dx 4 -d/dx p 1 du/dx + p 2 u u 0 = u 0 = u 1 = u 1 = 0 where p โ L 2 0 1 ร L 2 0 1 . We show that for near constant coefficients, if p is even about 1/2 and L p and L p have the same eigenvalues, then knowledge of the first coefficient uniquely determines the second up to average v
