The theory of Fermi liquid superconductivity combines two important theories for correlated electrons in metals, Landau's theory of Fermi liquids and the BCS theory of superconductivity. These lecture notes summarize the conceptual framework of the Fermi liquid theory of superconductivity, decribes the fundamental equations and their basis as an expansion in low-energy and long-wavelength scales compared to microscopic scales set by the normal metallic state, and finally recent applications of this theory to transport and vortex dynamics in layered, high Tc superconductors.
