Abstract

We analyze DESI DR2 data with a model-independent method and find that: (a) the expansion of the universe may speed up with a confidence level more than 2.3 [Formula: see text] at redshift [Formula: see text]; (b) the expansion of the universe may speed down with a confidence level greater than 1.7 [Formula: see text] at redshift [Formula: see text]; (c) [Formula: see text] with confidence level exceeding 1.6 [Formula: see text] at redshift [Formula: see text].
