2. Tsallis holographic dark energy in the Brans–Dicke cosmology / Ghaffari, S. ; Moradpour, H. ; Lobo, I. P. ; Graça, J. P. Morais ; et al
Using the Tsallis generalized entropy, holographic hypothesis and also considering the Hubble horizon as the IR cutoff, we build a holographic model for dark energy and study its cosmological consequences in the Brans–Dicke framework. [...]

3. Thermodynamic Analysis of Gravitational Field Equations in Lyra Manifold / Moradpour, H. ; Sadeghnezhad, N. ; Ghaffari, S. ; Jahan, A.
Considering the Einstein field equations in Lyra manifold and applying the unified first law of thermodynamics as well as the Clausius relation to the apparent horizon of FRW universe, we find the entropy of apparent horizon in Lyra manifold. [...]
