(This article belongs to the Special Issue Symmetry and Quantum Gravity)
quantum-gravity corrections (in the form of a minimal length) to the Feynman propagator for a free scalar particle in R D are shown to be the result of summing over all dimensions D D of R D , each summand taken in the absence of quantum gravity.
Keywords: Feynman propagators; quantum of length; quantum gravity Feynman propagators; quantum of length; quantum gravity
