Abstract
Following our earlier work (J. Phys. A, 38 (2005) 957; J. Math. Phys., 48 (2007) 052302), we derive noncommuting phase-space structures which are combinations of both the $\kappa $-Minkowski and the Snyder algebra by exploiting the reparametrisation symmetry of the recently proposed Lagrangian for a point particle (GHOSH S., Phys. Rev. D, 74 (2006) 084019) satisfying the exact Doubly Special Relativity dispersion relation in the Magueijo-Smolin framework.
