摘要：
本文基于非平衡Keldysh技术，对相互作用电子系统中体现精确守恒律的连续性方程进行了教学式推导。此项工作的目的是为将电子输运的流体力学方法推广到准粒子近似和Boltzmann动力学理论失效的强关联系统奠定基础。
英文摘要：
In this paper I present a pedagogical derivation of continuity equations manifesting exact conservation laws in an interacting electronic system based on the nonequilibrium Keldysh technique. The purpose of this exercise is to lay the groundwork for extending the hydrodynamic approach to electronic transport to strongly correlated systems where the quasiparticle approximation and Boltzmann kinetic theory fail.
