After dimensional reduction to three dimensions, the lowest order effective actions for pure gravity, M-theory and the Bosonic string admit an enhanced symmetry group. In this paper we initiate study of how this enhancement is affected by the inclusion of higher derivative terms. In particular we show that the coefficients of the scalar fields associated to the Cartan subalgebra are given by weights of the enhanced symmetry group.

Symmetries of non-maximal supergravities with higher-derivative corrections
Higher-derivative corrections explicitly break all hidden symmetry enhancements in the three-dimensional reductions of non-maximal supergravities.

The auxiliary-deformed Breitenlohner-Maison model: duality frames and higher-dimensional origin
Extends auxiliary deformations of the 2D BM model to the μ-frame and uplifts both frames to a 4D higher-derivative theory without manifest diffeomorphism invariance.

Integrable deformations of dimensionally reduced gravity
Auxiliary field and Yang-Baxter deformations of D=2 dimensionally reduced gravity are shown to admit flat Lax representations, with the auxiliary field case preserving the Hamiltonian integrability structure.
