Equation of state for dark energy in f(T) gravity

We study the cosmological evolutions of the equation of state for dark energy

'Teleparallel' Dark Energy

w_{\mathrm{DE}}

Observational constraints on teleparallel dark energy

in the exponential and logarithmic as well as their combination

Cosmological evolution in exponential gravity

theories. We show that the crossing of the phantom divide line of

Teleparallel dark energy with purely non-minimal coupling to gravity

w_{\mathrm{DE}} = -1

Generic feature of future crossing of phantom divide in viable f(R) gravity models

can be realized in the combined
