    • 我們畫了f(R)的matter power spectrum，並且考慮了有質量的微中子的情況。

    We study the matter power spectrum in cosmology based on the expo-
    nential f(R) gravity model by using the program, Modi cation of Growth
    with CAMB (MGCAMB). We also examine the e ect of the matter power
    spectrum when a massive neutrino is considered. By comparing the spectra
    between the theoretical expectations and the observation of the luminous
    red galaxies (lrg) from the Sloan Digital Sky Survey (SDSS) of the Seventh Data Release (DR7), we nd that the exponential f(R) gravity model is compatible with larger neutrino mass than the CDM model.
