摘要

对于参数 ℓ 的任意整数或半整数值，我们提出了在ℓ-共形牛顿-胡克群下不变的完美流体方程。对于 ℓ=32 的情况，构建了相应的守恒电荷，并建立了哈密顿公式。

Perfect fluid dynamics with conformal Newton-Hooke symmetries

Perfect fluid equations are formulated which are invariant under the ℓ-conformal Newton-Hooke group for an arbitrary integer or half-integer value of the parameter ℓ. For

ℓ = \frac{3}{2}

the corresponding conserved charges are constructed and the Hamiltonian formulation is built.

期刊介绍： Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
