dc.description.abstractThe exact bound state spectrum of rationally extended shape invariant real as well as symmetric complex potentials is obtained by using potential group approach. The generators of the potential groups are modified by introducing a new operator to express the Hamiltonian corresponding to these extended potentials in terms of Casimir operators. Connection between the potential algebra and the shape invariance is elucidated.en_US
