Abstract
A key basis for seeking periodic solutions of the Camassa-Holm equation is to understand the associated spectral problemy'=y+lambdamy.The periodic spectrum can be recovered from the norming constants and the elements of the auxiliary spectrum. The potential can then be reconstructed from the periodic spectrum. A necessary and sufficient condition for exponential decrease of the widths lambda2n-lambda2n-1for a sequence 0
