Born-Infeld gravity in Weitzenböck spacetime

Using the teleparallel equivalent of general relativity formulated in Weitzenböck spacetime, we thoroughly explore a kind of Born-Infeld regular gravity leading to second order field equations for the vielbein components. We explicitly solve the equations of motion for two examples: the extended Bañ...
