非对易标量场理论的对称性

Symmetries of noncommutative scalar field theory

Axel de Goursac, Jean-Christophe Wallet

摘要:

研究了具有欧氏标积和一般辛形式的Moyal空间上具有调和项的标量场理论的对称性。经典作用在正交群下是不变的,如果这个群也作用在辛结构上。我们发现,正交群下的不变性也可以恢复在量子水平上通过限制辛结构到一个特定的轨道。

英文摘要:

We investigate symmetries of the scalar field theory with harmonic term on the Moyal space with euclidean scalar product and general symplectic form. The classical action is invariant under the orthogonal group if this group acts also on the symplectic structure. We find that the invariance under the orthogonal group can be restored also at the quantum level by restricting the symplectic structures to a particular orbit.
