A systematic procedure to study one-dimensional Schroedinger equation with
position-dependent effective mass (PDEM) in the kinetic energy operator is
explored. We show that any constant mass Schroedinger equation can be
coordinate
transformed in terms of some mass function such that the resulting form
matches with
the PDEM equation and the ambiguity parameters are decoupled in the
potential
term. This enables us to derive many exact results including those
related to
isospectrality. We also seek interesting connections with the so(2,1)
algebra by
choosing appropriate forms of the underlying generators.
