Abstract: | We study the matter stability in modified teleparallel gravity or f(T) theories. We show that there is no Dolgov–Kawasaki instability in these types of modified teleparallel gravity theories. This gives for the f(T) theories a great advantage over their f(R) counterparts because from the stability point of view there isn?t any limit on the form of functions that can be chosen. |
