Noncommutative gauge theory using covariant star product defined between Lie-valued differential forms

M. Chaichian, M. Oksanen, A. Tureanu, G. Zet

摘要:

我们用协变星积发展了一个内规范理论。时空是一个只具有挠率而没有曲率的辛流形。结果表明,为了保证星积的结合性所施加的限制,时空的挠率必须是协变常数。一个说明性的例子,它的结论是,在这种情况下,必要的条件,以定义一个协变星产品的辛流形上完全确定其连接。

英文摘要:

We develop an internal gauge theory using a covariant star product. The space-time is a symplectic manifold endowed only with torsion but no curvature. It is shown that, in order to assure the restrictions imposed by the associativity property of the star product, the torsion of the space-time has to be covariant constant. An illustrative example is given and it is concluded that in this case the conditions necessary to define a covariant star product on a symplectic manifold completely determine its connection.
