S- and T-self-dualities in dilatonic $$f(R)$$ f ( R ) theories
Abstract We search for theories, in general spacetime dimensions, that would incorporate a dilaton and higher powers of the scalar Ricci curvature such that they have exact S- or T-self-dualities. The theories we find are free of Ostrogradsky instabilities. We also show that within the framework we...
