- Statefinder Revisited Emille E. O. Ishida Física, Astronomía y Matemáticas The quality of supernova data will dramatically increase in the next few years by new experiments that willadd high-redshift supernova to the currently known ones. In order to use this new data to discriminate betweendifferent dark energy models, the statefinder diagnostic was suggested [1] and investigated by Alam et al.[3] inthe light of the proposed SuperNova Acceleration Probe (SNAP) satellite. By making use of the same procedurepresented by these authors, we compare their analyzes with ours, which shows a more realistic supernovaeredshift distribution and do not assume that the intercept is known. We also analyzed the behavior of thestatefinder pair {r,s} and the alternative pair {s,q} in the presence of offset errors. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435745 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4B Vol.35
