Abstract

Relations connecting GRB quantities can be used to constrain cosmographic parameters of the Hubble law at medium-high redshifts. We consider a sample of 64 GRBs to construct the luminosity distance - redshift relation and derive the values of the parameters q_0$, j_0 and s_0. The results, calibrated by SNeIa data, agree with the $\Lambda$CDM model.
