- Abstract: We show in this paper that the basic representations of position and momentum
in a quantum mechanical system, that are guided by a generalized uncertainty
principle and lead to a corresponding one-parameter eigenvalue problem, can be
interpreted in terms of an extended Sch\"{r}odinger equation embodying
momentum-dependent mass. Some simple consequences are pointed out.
