We construct a holographic dark energy model in a braneworld setup where gravity is induced on the brane embedded in a bulk with the Gauss–Bonnet curvature term. We include possible modifications of the induced gravity and its coupling with a canonical scalar field on the brane. Through a perturbational approach to calculating the effective gravitation constant on the brane, we examine the outcome of this model as a candidate for holographic dark energy.

Commonly used boundary conditions in reconstructing f(T) gravity from holographic Ricci dark energy (RDE) model are found to cause some problem, we therefore propose new boundary conditions in this paper. By reconstructing f(T) gravity from the RDE with these new boundary conditions, we show that the new ones are better than the present commonly used ones since they can give the physically expected information, which is lost when the commonly used ones are taken in the reconstruction, of the resulting f(T) theory. Thus, the new boundary conditions proposed here are more suitable for the reconstruction of f(T) gravity.
