非相对论共形群及其动力学实现

Nonrelativistic conformal groups and their dynamical realizations

K. Andrzejewski, J. Gonera, P. Maslanka

摘要:

分析了指数为l=N/2的非相对论共形群。在中心延拓参数化的“质量”非零的假设下,对余伴随轨道进行了分类,并用方便的变量描述了余伴随轨道。结果表明,在Ostrogradski框架下,相应的动力学系统描述了服从(N+1)阶运动方程的非相对论性粒子.作为特殊情况,得到了N=1(l=1/2)时的Schroedinger群和标准牛顿方程.

英文摘要:

Nonrelativistic conformal groups, indexed by l=N/2, are analyzed. Under the assumption that the "mass" parametrizing the central extension is nonvanishing the coadjoint orbits are classified and described in terms of convenient variables. It is shown that the corresponding dynamical system describes, within Ostrogradski framework, the nonrelativistic particle obeying (N+1)-th order equation of motion. As a special case, the Schroedinger group and the standard Newton equations are obtained for N=1 (l=1/2).
