Spherically Symmetric Solutions on a Non-Trivial Frame in f(T) Theories of Gravity

         

摘要

A new solution with constant torsion is derived using the field equations of f(T).Asymptotic forms of energy density,radial and transversal pressures are shown to meet the standard energy conditions,i.e.,weak and 'null' energy conditions according to some restrictions on T0,f(T0) and fT(T0). Other solutions are obtained for vanishing radial pressure and for specific choices of f(T).The physics relevant to the resulting models is discussed.
