,Spectral Theory for the Schrödinger Operator with a Complex-Valued Periodic Potential,ed potential . by introducing new concepts and approaches. First, in the introduction section, we introduce the required notations and discuss the results of this chapter. Then, in Sect. ., we study the Floquet solutions of the equation . and consider the general property of the spectrum of .(.). In

On the Special Potentials,stigate the operator .(.) with complex-valued even potential . and prove that it may has at most finite number of ESS. In Sect. ., we investigate the spectrum and spectral singularities of the operator .(.) with a periodic PT-symmetric complex-valued potential . . A basic mathematical question of PT

,On the Mathieu-Schrödinger Operator,st, we investigate the asymptotic formulas for the isolated Bloch eigenvalues and find a condition for the isospectrality. Then we consider the asymptotic formulas for the pair of the Bloch eigenvalues and find a necessary and sufficient condition on the potential for which . has no spectral singula
