Quasianalytic classes and isospectral Hill’s operators. (English) Zbl 0811.34072

Marchenko, V. A. (ed.), Spectral operator theory and related topics. Collection of papers. Providence, RI: American Mathematical Society. Adv. Sov. Math. 19, 27-39 (1994).
The paper is devoted to the theory of quasianalytic classes and isospectral Hill’s operators. The main result is a criterion for unique recovery in terms of smoothness of potentials. New results concerning the relationship between the rate of decay of gap lengths and smoothness of a periodic potential are obtained.
