P-adic multiple zeta values, pro-unipotent harmonic actions and multiple harmonic values
David Jarossay (University of Geneva)
We will compute the p-adic analogues of multiple zeta values in a way which keeps track of the motivic Galois action on the pro-unipotent fundamental groupoid of the projective line minus three points. This will be expressed by means of new objects which we will call pro-unipotent harmonic actions.
