Inverse problems for differential operators with two delays larger than half the length of the interval and Dirichlet conditions

Abstract

This paper deals with nonself-adjoint second-order differential operators with two constant delays from $frac{mathrmpi}2,;mathrmpi$and two real-valued potentials from $L_2left[0,mathrmpiright]$ . An inverse spectral problem of recovering operators from the spectra offour boundary value problems is studied.
