| Abstract | The Hubble constant (H-0) is a crucial parameter in cosmology. Different cosmic observations have resulted in varying estimates results for H-0 that is the well-known H-0 tension. To address this issue, it is beneficial to use other data set to constrain H 0. In this paper, via the cosmographic approach based on the Friedman-Lemaitre-Robertson-Walker (FLRW) metric to the dispersion measure (DM) of the intergalactic medium DMIGM(z) of fast radio bursts (FRBs), we obtain the Taylor expansion of (DMIGM (z)) in terms of redshift z. Utilizing the uncalibrated type Ia supernaove (SNe Ia) and 18 localized FRBs, we give the cosmological constraints, H-0 = 65.5(-5.4)(+6.4) km s(1) (68 per cent CL), cosmological deceleration parameter q(0) = -0.50 +/- 0.20 and the jerk parameter j(0) = -0.1(-2.5)(+2.0). To demonstrate the impact of parameter degeneracies on our analysis methods, we compare the results using three different forms of fIGM(z) and two different prior distributions of Omega(b, 0). After that, we find that the uncertainty in H-0 is not significantly affected by the width of the prior interval of f(IGM) (z) and Omega(b, 0), but the mean value is influenced by the priors for f(IGM)(z) and Omega(b, 0) due to parameter degeneracies with H-0. Employing f(IGM (z)) that evolves with redshift, we obtain H-0 = 69.0(5.7)(+6.7)km s(-1) Mpc(-1). In addition, the mock analyses provide a posterior estimation of H-0 with an accuracy of 4.6 per cent and higher precision for q(0) and j(0) in the near future. |
