By using the intertwining operator technique we show how to
construct the quantum well potential with a desired spectrum for
the Schrödinger equation with a position-dependent effective
mass. The first- and second-order Darboux transformations,
supersymmetry, chain of transformations are considered for the
Schrödinger equation with a nonconstant mass. An interrelation
is established between the differential and integral
transformation operators. The method allows one to generate
potentials with additional and with removal bound states in
comparison with the spectrum of an initial potential as well as to
construct phase-equivalent potentials.
