(Lambda) over dot proportional to H(3), in the context of 5- dimensional space time. Time-dependent form of equation of state parameter w is derived along with a possible signature flip of deceleration parameter q. It is also observed that a present age of the Universe, calculated for some specific values of parameter agrees very well with the observational data.eninfo:eu-repo/semantics/closedAccessDark EnergyVariable LambdaLambda-CDM CosmologyArticle10.1007/s10773-008-9810-24823733792-s2.0-60449114357Q3WOS:000263378600008Q3
