             abstract = "In this work, we obtain measurements of the Hubble constant in the 
                         context of modified gravity theories. We set up our theoretical 
                         framework by considering viable cosmological f(R) and f (T) 
                         models, and we analyzed them through the use of geometrical 
                         datasets obtained in a model-independent way, namely, 
                         gravitationally lensed quasars with measured time delays, standard 
                         clocks from cosmic chronometers, and standard candles from the 
                         Pantheon Supernovae Ia sample. We find H-0 = (72.4 +/- 1.4) km 
                         s(-1) Mpc(-1) and H-0 = (71.5 +/- 1.3) km s(-1) Mpc(-1) for the 
                         f(R) and f (T) models, respectively. Our results represent 1.9% 
                         and 1.8% measurements of the Hubble constant, which are fully 
                         consistent with the local estimate of H o by the Hubble Space 
                         Telescope. We do not find significant departures from general 
                         relativity, as our study shows that the characteristic parameters 
                         of the extensions of gravity beyond general relativity are 
                         compatible with the ACDM cosmology. Moreover, within the standard 
                         cosmological framework, our full joint analysis suggests that it 
                         is possible to measure the dark energy equation of state parameter 
                         at 1.2% accuracy, although we fmd no statistical evidence for 
                         deviations from the cosmological constant case.",
