ABSTRACT AND APPLIED ANALYSIS, 2013 (SCI-Expanded)
An inverse problem for Dirac differential operators with discontinuity conditions and discontinuous coefficient is studied. It is shown by Hochstadt and Lieberman's method that if the potential function p(x) in Omega(x) is prescribed over the interval (pi/2,pi), then a single spectrum suffices to determine p(x) on the interval (0,pi) and it is also shown here that rho(x) is uniquely determined by a spectrum.
