Abstract

We consider the issue of deriving superintegrable systems with position dependent mass (PDM) in two dimensions from certain known superintegrable systems using the recently introduced method of master symmetries and complex factorization by M. Ranada \citeRana1,Rana2,Rana3,Rana4. We introduce a noncanonical transformation to map the Hamiltonian of the PDM systems to that of ordinary unit mass systems. We observe a duality between these systems. We also study Tsiganov's method \citeTsiganov1,Tsiganov2,Tsiganov3,Tsiganov4 to derive polynomial integrals of motion using addition theorems for the action-angle variables using famous Chebyshev's theorem on binomial differentials. We compare Tsiganov's method of generating an additional integral of motion with that of Ranada's master symmetry method.
