Description
In this talk, I will revisit the evolution of generalised parton distributions (GPDs) at leading order in the strong coupling constant $\alpha_s$ for all of the twist-2 quark and gluon operators. I will present a rederivation of the one-loop evolution kernels, expressing them in a form suitable for implementation, and check analytically that some basic properties, such as DGLAP/ERBL limits and polynomiality conservation, are fulfilled. I will also present a number of numerical results obtained with a public implementation of the evolution in the library APFEL++ and available within the PARTONS framework.
