U(u(2))背景下的量子几何和量子化。非对易狄拉克算符

Quantum geometry and quantization on U(u(2)) background. Noncommutative Dirac monopole

Dimitri Gurevich, Pavel Saponov

摘要:

在我们以前的出版物中,我们介绍了微分学上的包络代数U(gl(m))类似于通常的演算上的交换代数Sym(gl(m))。我们微积分的主要成分是量子偏导数,它在经典极限中变成通常的偏导数。在特殊情况下,m=2,我们延长了这个演算上的一个中心扩张A的代数U(gl(2))。本文考虑代数A的斜域上的量子偏导数的进一步扩张问题,并定义了相应的de Rham复形。作为微分学的一个应用,我们提出了一种将定义在Sym(u(2))上的动力学模型转化为代数U(u(2))的方法(我们称这个过程为非对易位形空间量子化)。在这个意义上,我们证明了狄拉克定理,并找到了这个模型的解。

英文摘要:

In our previous publications we introduced differential calculus on the enveloping algebras U(gl(m)) similar to the usual calculus on the commutative algebra Sym(gl(m)). The main ingredient of our calculus are quantum partial derivatives which turn into the usual partial derivatives in the classical limit. In the particular case m=2 we prolonged this calculus on a central extension A of the algebra U(gl(2)). In the present paper we consider the problem of a further extension of the quantum partial derivatives on the skew-field of the algebra A and define the corresponding de Rham complex. As an application of the differential calculus we suggest a method of transferring dynamical models defined on Sym(u(2)) to the algebra U(u(2)) (we call this procedure the quantization with noncommutative configuration space). In this sense we quantize the Dirac monopole and find a solution of this model.
