标题： Two--Dimensional BF Model Quantized in the Axial Gauge

摘要： 二维拓扑BF模型在轴向规范下被量子化。 我们证明该理论是平凡的紫外有限的，并且二维标量场传播子的通常红外问题被轴向规范固有的易于解决的长距离问题所取代。 还将证明与三维情况相反，作用原理不能完全由表达模型对称性的各种Ward恒等式代替；需要一些运动方程。 显示英文摘要

摘要： The two--dimensional topological BF model is quantized in the axial gauge. We show that this theory is trivially ultraviolet finite and that the usual infrared problem of the propagator of the scalar field in two dimensions is replaced by an easily solvable long distances problem inherent to the axial gauge. It will also be shown that contrarily to the 3--dimensional case, the action principle cannot be completely replaced by the various Ward identities expressing the symmetries of the model; some of the equation of motion are needed.
