Position-dependent mass Lagrangians: nonlocal transformations, Euler-Lagrange invariance and exact solvability

Mustafa, Omar (IOP Publishing, 2015)

A general nonlocal point transformation for position-dependent mass (PDM) Lagrangians and their mapping into a 'constant unit-mass' Lagrangians in the generalized coordinates is introduced. The conditions on the invariance ...
