Tóm tắt/Abstract:
Although derivation of Hawking fluxes has been already performed around 1974 by Hawking based on the pair-creation in the vicinity of the near-horizon region, around 2005 Hawking fluxes have been again derived based on the anomaly-free condition [1,2]. This way would be very intriguing, because it will suggest the following two points:

1) Hawking fluxes might be the fluxes appearing as the quantum tunneling in order to compensate for the deficit of outgoing modes on the horizon so as to be anomaly-free at the semi-classical level.

2) A picture in which Hawking fluxes and Bekenstein-Hawking entropy are drown uniformly.

In this seminar, based on my study as in the title, I would like to introduce the way for the derivation of Hawking fluxes based on anomaly-free condition and the physics mentioned above.

Further I will give a comment about which models proposed in [3] as the regular black hole with a time-delay are physically consistent. This would be beneficial for the future works based on the regular black holes with a time-delay in [3].
