Weak field limit and gravitational waves in f(T, B) teleparallel gravity
Abstract We derive the gravitational waves for $$f\left( T, B\right) $$ fT,B gravity which is an extension of teleparallel gravity and demonstrate that it is equivalent to f(R) gravity by linearized the field equations in the weak field limit approximation. f(T, B) gravity shows three polarizations:...
