We study the doping evolution of the electronic structure in the normal phase of high-Tc cuprates. The electronic structure and the Fermi surface of cuprates with a single CuO2 layer in the unit cell like La2-xSrxCuO4 have been calculated by the LDA+GTB method in the regime of strong electron correl...
