摘要: We study the cosmological evolutions of equation state for dark energy wDE in exponential and logarithmic as well their combination f(T) theories. show that crossing phantom divide line = −1 can be realized combined theory even though it cannot or theory. In particular, is from > to < −1, opposite manner f(R) gravity models. also demonstrate this feature favored by recent observational data.
