Description
This work has an interesting approach to estimate the spatial curvature $\Omega_k$ from data independently of dynamical models is suggested, it was done through three kinematic parameterizations of the comoving distance ($D_{C}(z)$) with second degree polynomial, of the Hubble parameter ($H(z)$) with a second degree polynomial and of the deceleration parameter ($q(z)$) with first order polynomial. All these parameterizations are done as function of redshift $z$. We used SNe Ia dataset from Pantheon compilation with 1048 distance moduli estimated on the range $0.01
