Published online by Cambridge University Press: 01 July 1997
Abstract
Requirements for boundary conditions are found which imply sharp by order estimates in L∞-metrics of eigenfunctions of the ordinary differential operator

It is shown that the inequalities

for the eigenfunctions {yλ} yield certain restrictions on the spectrum.
