On the shape of a D-brane bound state and its topology change
Tatsuo Azeyanagi, Masanori Hanada, Tomoyoshi Hirata +1
As is well known, coordinates of D-branes are described by NxN matrices. From generic non-commuting matrices, it is difficult to extract physics, for example, the shape of the dist…
On Matrix Model Formulations of Noncommutative Yang-Mills Theories
Tatsuo Azeyanagi, Masanori Hanada, Tomoyoshi Hirata
We study stability of noncommutative spaces in matrix models and discuss the continuum limit which leads to noncommutative Yang-Mills theories (NCYM). It turns out that most of non…
Higher Derivative Correction to the Hawking Flux via Trace Anomaly
Akihide Shirasaka, Tomoyoshi Hirata
In this paper we derive Hawking radiation of black holes with higher derivative corrections by the method of trace anomaly. Firstly we derive Hawking radiation for general spherica…
