Gravitational semiclassical theorems for a black hole
Comments: 8 pages, 4 figures, version accepted for publication in JHEP

We study the Hawking radiation of a black hole in the context of the semiclassical theorems for a black hole. We show that the Hawking radiation is in exact agreement with the observed thermalization period of the black hole. We also discuss the Hawking radiation as a potential for the ground state energy of the black hole.

Internal symmetry of the $N$-flavored CHL model
Comments: 9 pages, 2 figures, this is a refs. in the Proc. of the XIIth International Conference on Mathematical Physics, 2017, and the supplementary material is available at

We study the CHL model on a model with a missing $N$-flavor inside the $3+1$-dimensional space. We find that the internal symmetry of the $N$-flavored CHL model is non-compact. We also remark on the connection between the $N$-flavored CHL model and the non-compact CHL model and the $N$-flavored CHL model.
