## Special Issue Information

Dear Colleagues,

Almost thirty years after the introduction of the famous Bekenstein–Hawking formula [Bekenstein, J.D. *Phys. Rev. ***1973**, *D 7*, 949. Hawking, S.W. *Comm. Math. Phys. ***1975**, *43*, 199.], relating the entropy of a black hole and its area, the thermodynamics of such objects still attracts research in this direction. One reason is due to the lack of a Quantum Gravity theory that should be able to explain black hole physics. Another reason comes from the fact that Hawking radiation develops modes of arbitrarily high frequency near the horizon. It is clear that the subject of studying Entropy in Quantum Gravity is far to be exhausted. This special section would focus on different contributions and approaches by some of the leading researchers in this field.

- scope: to provide a set of essays to illustrate the different approaches in different areas of Quantum Gravity that try to explain the connection between entropy and geometry.
- motivation: the motivation for this issue comes out of a discussion in different workshops and conferences concerning quantum gravity. These different discussions illustrated needs for clarification and interpretation of the different view angles of Entropy-Area relation and Entropy in the context of Quantum Gravity. The invited and contributed essays of this special section would help to clarify this important theoretical foundation.
