Abstract

I introduce the spatial curvature effects inside the formalism of Relative Locality as a non-commutative structure of the momentum space in agreement with the very well known concepts of Quantum Groups. This gives a natural red-shift effect in agreement with an extended version of the Generalized Uncertainty Principle (GUP) and in agreement with the standard notions of curvature inside General Relativity. I then introduce the concept of Relative Co-locality as a reinterpretation of the usual notions of spacetime curvature. From this redefinition, I obtain the momentum space curvature effects as a non-commutativity in position space. This introduce a natural blue-shift effect in agreement with the extended version of GUP. Both effects, Relative locality and Co-locality are dual each other inside the formalism of quantum groups SUq(n)SU_q(n) symmetric Heisenberg algebras and their q-Bargmann Fock representations. When Relative locality and Co-locality are introduced, the q-deformation parameter takes the form q1+pxrΛmplq\approx 1+\sqrt{\frac{\vert p\vert \vert x\vert}{r_\Lambda m_{pl}}} with the spatial curvature effects in Relative Locality appearing like ΔXxmplΔP\Delta X\approx \frac{\vert x\vert}{m_{pl}}\Delta P and the momentum curvature effects in Relative Co-locality appearing like ΔPprΛΔX\Delta P\approx \frac{\vert p\vert}{r_\Lambda}\Delta X, where rΛ=1Λr_\Lambda=\frac{1}{\sqrt{\Lambda}} is the scale defined by the Cosmological Constant Λ\Lambda, mplm_{pl} is the Planck mass and ΔX/ΔP\Delta X/\Delta P is a scale of position/momentum or time/energy associated with the event, p and x are the momentum and position of the observer relative to the event.
