物理规律的不变性与守恒定律
1
作者 张大明 《河南广播电视大学学报》 1996年第Z1期54-55,45,共3页
本文论述量子场论中由物理规律的不变性导出守恒定律的正则形式。指出,若发现某些不可观察量变为可观察量,亦即某些对称性被发现在某范围内是不对称的,则可能导致相应守恒律的破坏。

In a recent paper the author constructed a continuous map from the configuration space of n distinct ordered points in 3-space to the flag manifold of the unitary group U(n), which is compatible with the action of the symmetric group. This map is also compatible with appropriate actions of the rotation group SO(3). In this paper the author studies the induced homomorphism in SO(3)-equivariant cohomology and shows that this contains much interesting information involving representations of the symmetric group. 展开更多
