A quasiparticle structure calculation for Sr2RuO4 is performed. Starting from the band structure determined in the local density formalism, the Dyson's equation with self-energies arising from the Hubbard Hamiltonian, is solved by diagonalizing the Green's function in k-space. The density of states is obtained by considering the renormalization factor and the lifetimes of the quasiparticle states. We also obtain the Fermi surface without and with the inclusion of the strong correlations effects.
