摘要：
In this paper I present a pedagogical derivation of continu-ity equations manifesting exact conservation laws in an inter-acting electronic system based on the nonequilibrium Keldysh technique. The purpose of this exercise is to lay the ground-work for extending the hydrodynamic approach to electronic transport to strongly correlated systems where the quasiparticle approximation and Boltzmann kinetic theory fail.& COPY; 2023 Elsevier Inc.
