# New examples of Hawking radiation from acoustic black holes

@article{Eskin2019NewEO, title={New examples of Hawking radiation from acoustic black holes}, author={G. Eskin}, journal={Contemporary Mathematics}, year={2019} }

Rotating acoustic metrics may have black holes inside the ergosphere. Simple cases of acoustic black holes were studied in the references [21], [4]. In the present paper we study the Hawking radiation for more complicated cases of acoustic black holes including black holes that have corner points.
