Reconstruction of the dynamics of Universe

Shant Baghramian- SUT

Abstract:
In this talk, we propose an inverse method to reconstruct the Modified gravity action in Palatini formalism, using the dynamics of universe. In the next step we use the reconstruction method to extract the dynamics of universe from observational SNIa data. Also we check the viability of reconstruction method and impose conditions in which this procedure can be useful. Finally we introduce two diagnosis in order to distinguish between LCDM model and alternative models of accelerating universe.
