Hamilton力学的非惯性对称群

Noninertial Symmetry Group of Hamilton's Mechanics

Stephen G. Low

摘要:

我们给出了Hamilton方程的一个新的推导,证明了它们有一个对称群Sp(2n)* sH(n). Sp(2n)是辛群,H(n)在数学上是由速度、力和功率参数化的Weyl-Heisenberg群,其中功率是群的中心元素。我们给出了Hamilton方程的一个新的推导,证明了它们有一个对称群Sp(2n)* sH(n).群Sp(2n)是实非紧辛群,H(n)在数学上是由速度、力和功率参数化的Weyl-Heisenberg群,其中功率是群的中心元素。齐次伽利略群SO(n)*s A(n),其中特殊正交群SO(n)由旋转参数化,阿贝尔群A(n)由速度参数化,是惯性子群。

英文摘要:

We present a new derivation of Hamilton's equations that shows that they have a symmetry group Sp(2n) *s H(n). Sp(2n) is the symplectic group and H(n) is mathematically a Weyl-Heisenberg group that is parameterized by velocity, force and power where power is the central element of the group. We present a new derivation of Hamilton's equations that shows that they have a symmetry group Sp(2n) *s H(n). The group Sp(2n) is the real noncompact symplectic group and H(n) is mathematically a Weyl-Heisenberg group that is parameterized by velocity, force and power where power is the central element of the group. The homogeneous Galilei group SO(n) *s A(n), where the special orthogonal group SO(n) is parameterized by rotations and the abelian group A(n)is parameterized by velocity, is the inertial subgroup.
