Research Abstract

We studied the Hawking radiation by using effective theories which appear near the event horizon. We gave explicit expressions for noncommutative products on CPN and CHN by deformation quantization in order to investigate effects of noncommutativities of space-time. Fock representations for these noncommutative products were constructed and the algebraic structure of functions under the products was explicitly clarified. These noncommutative spaces include the fuzzy CPN which was given by using matrix models as a specific case.
