Inequalities among eigenvalues of Sturm Liouville equations with periodic coefficients

It is well known that for h-periodic coefficients, every periodic eigenvalue on every interval [a,a+kh], k=2,3,4,..., is also an eigenvalue on the interval [a,a+h] of a periodic, semi-periodic or complex self-adjoint boundary condition. Here we give an explicit 1-1 correspondence between these e...
