仿射协变星积与非对易引力

Diffeomorphism covariant star products and noncommutative gravity

D. V. Vassilevich

摘要:

使用一个同态协变星积,使我们能够构造非交换辛流形上的同态不变引力,而不扭曲对称性。作为一个例子,我们构造了所有二维非交换引力模型的非交换变形,从而克服了早期方法的一些困难。其中一个模型似乎是可积的。我们找到了这个模型的所有经典解,并讨论了它们的性质。

英文摘要:

The use of a diffeomorphism covariant star product enables us to construct diffeomorphism invariant gravities on noncommutative symplectic manifolds without twisting the symmetries. As an example, we construct noncommutative deformations of all two-dimensional dilaton gravity models thus overcoming some difficulties of earlier approaches. One of such models appears to be integrable. We find all classical solutions of this model and discuss their properties.
