Abstract
Excitations of the strongly correlated electrons within the Cu – O planes can be studied by numerical methods. The characteristic properties of the one hole (electron) spectral density can be rederived by analytic methods based on projection techniques, and as far as the coherent part of the motion of holes is concerned by a tight-binding-like approach using string states.
