非对称应力张量磁流体力学

Magnetic hydrodynamics with asymmetric stress tensor

Yuly Billig

摘要:

本文研究了带应力张量的磁流体力学方程。我们将该系统解释为与具有非平凡2-上循环的向量场李代数的阿贝尔扩展相关的广义欧拉方程。我们用李代数方法证明了能量守恒定律和交叉螺旋度守恒。

英文摘要:

In this paper we study equations of magnetic hydrodynamics with a stress tensor. We interpret this system as the generalized Euler equation associated with an abelian extension of the Lie algebra of vector fields with a non-trivial 2-cocycle. We use the Lie algebra approach to prove the energy conservation law and the conservation of cross-helicity.
