From spacetime symmetries to "good tetrads" in teleparallel gravity — •Manuel Hohmann — Universität Tartu, Tartu, Estland

General teleparallel theories of gravity, which have originally been formulated in terms of a tetrad only, can be formulated covariantly with respect to local Lorentz transformations by introducing a flat spin connection as an additional gauge degree of freedom. The corresponding field equations are similar for a wide range of theories and can be solved either by a suitable spin connection, or in the Weitzenböck gauge of vanishing spin connection by a suitable ("good") tetrad. We discuss the geometric meaning of this condition, and show how spacetime symmetries can aid in solving the connection field equations. A number of example solutions will be provided.
