this paper uses the tsuji’s characteristic to investigate the uniqueness of transcen- dental meromorphic function with shared values in an angular domain dealing with the multiple values which improve a result of j. zheng.

Abstract The cosmological jerk parameter j is reconstructed in a non-parametric way from observational data independent of fiducial model. Cosmic Chronometer as well the Supernovae (the Pantheon compilation) are used for purpose. values found to be consistent with standard $$\Lambda $$ ? CDM model within $$2\...
