  These lecture notes discuss several topics in the physics of cosmic structure
formation starting from the evolution of small-amplitude fluctuations in the
radiation-dominated era. The topics include relativistic cosmological
perturbation theory with the scalar-vector-tensor decomposition, the evolution
of adiabatic and isentropic initial fluctuations, microwave background
anisotropy, spatial and angular power spectra, the cold dark matter linear
transfer function, Press-Schechter theory, and a brief introduction to
numerical simulation methods.
