相对论流体的广义欧拉坐标:哈密顿静止标架瞬时形式,相对变量,转动运动学

Generalized Eulerian Coordinates for Relativistic Fluids: Hamiltonian Rest-Frame Instant Form, Relative Variables, Rotational Kinematics

David Alba, Luca Lusanna

摘要:

我们研究了一种新的相对论性理想流体在新的广义欧拉位形坐标下的静止标架瞬时形式。在分离相对论质心和Wigner超平面上的相对变量后,引入动力学体标架,定义了流体的取向和形状变量.最后我们定义了流体的狄克逊多极子。

英文摘要:

We study the rest-frame instant form of a new formulation of relativistic perfect fluids in terms of new generalized Eulerian configuration coordinates. After the separation of the relativistic center of mass from the relative variables on the Wigner hyper-planes, we define orientational and shape variables for the fluid, viewed as a relativistic extended deformable body, by introducing dynamical body frames. Finally we define Dixon's multipoles for the fluid.
