摘要:

我们发展了弱指数李群余切丛上非形式形变量化的完整理论。引入了一个适当的星积积分公式,以及一个使星积良定义的合适函数空间。该函数空间成为Frechet代数以及预C*-代数。证明了星积的基本性质,并给出了星积到Hilbert代数和分布代数的延拓。构造了可观测量的C*-代数和态空间。此外,给出了位置空间中的算子表示。最后,给出了弱指数李群的例子。

英文摘要:

We develop a complete theory of non-formal deformation quantization on the cotangent bundle of a weakly exponential Lie group. An appropriate integral formula for the star-product is introduced together with a suitable space of functions on which the star-product is well defined. This space of functions becomes a Frechet algebra as well as a pre-C*-algebra. Basic properties of the star-product are proved and the extension of the star-product to a Hilbert algebra and an algebra of distributions is given. A C*-algebra of observables and a space of states are constructed. Moreover, an operator representation in position space is presented. Finally, examples of weakly exponential Lie groups are given.
