Finite-density systems can be explored with lattice QCD through the calculation of multihadron correlation functions. Recently, systems with up to 12 pi(+)'s or K+'s have been studied to determine the 3-pi(+) and 3-K+ interactions, and the corresponding chemical potentials have been determined as a function of density. We derive recursion relations between correlation functions that allow this work to be extended to systems of arbitrary numbers of mesons and to systems containing many different types of mesons, such as pi(+)'s, K+'s, (D) over bar (0)'s, and B+'s. These relations allow for the study of finite-density systems in arbitrary volumes and for the study of high-density systems.
