DESCRIPTION:Speakers: Yen Chin Ong (Nanjing University of Aeronautics and 
 Astronautics)\nI will review the recently proposed GEVAG (generalized entr
 opy and varying-G) theory. This theory gives a consistent treatment of how
  the field equation of gravity should be changed if the area law of horizo
 n entropy is modified\, namely that gravitational constant G is now area-d
 ependent\, the functional form of which depends on the specific modificati
 ons of the entropy. Specifically\, GEVAG was able to prevent the violation
  of the Bekenstein bound\, known to plague various generalized entropies l
 ike Tsallis entropy. When applied to the quantum gravity logarithmic corre
 ction\, the framework managed to derive a modified Hawking temperature tha
 t was previously obtained in the GUP (generalized uncertainty principle) l
 iterature\, but now without explicitly utilizing GUP. This circumvents the
  known problems in the GUP literature that heuristic derivations are often
  unreliable. I will briefly mention how these affect early time cosmology.
