Renormalization on the fuzzy sphere
Kohta Hatakeyama, Asato Tsuchiya, Kazushi Yamashiro
We study renormalization on the fuzzy sphere, which is a typical example of non-commutative spaces. We numerically simulate a scalar field theory on the fuzzy sphere, which is desc…

Equivalence of large- gauge theories on a group manifold and its coset space
Kohta Hatakeyama, Asato Tsuchiya
It was shown in arXiv:0912.1456 that the large- reduction holds on group manifolds in the sense that a large- gauge theory on a group manifold is realized by a matrix model w…

Renormalization on the fuzzy sphere
Kohta Hatakeyama, Asato Tsuchiya, Kazushi Yamashiro
We study renormalization on the fuzzy sphere. We numerically simulate a scalar field theory on it, which is described by a Hermitian matrix model. We show that correlation function…
