Rm. Santilli, ORIGIN, PROBLEMATIC ASPECTS AND INVARIANT FORMULATION OF Q-, K- AND OTHER QUANTUM DEFORMATIONS, Modern physics letters A, 13(4), 1998, pp. 327-335
In this letter we indicate some of the first references on quantum def
ormations, we point out their physical problematic aspects and outline
their invariant formulation which appears to be unknown in the rather
vast literature in the field.
