On perturbations of the spectrum of one-dimensional PT-symmetric periodic Schrodinger operator

P. G. Grinevich, I. A. Taimanov

For PT-symmetric periodic Schrodinger operator, which is a small perturbation of the zero potential, we calculate the spectrum and the divisor of zeroes of the Bloch function in th…
