[en] The formation of p- and d-wave superconducting ground states on a square lattice is studied within the BCS formalism and a generalized Hubbard model, in which a second-neighbor correlated hopping (Δt₃) is included in addition to the on site and nearest neighbor repulsions. The triplet superconductivity is obtained when a small distortion of the right angles in the square lattice is introduced. This distortion can be characterized by the difference between the values of Δt₃^± in the x ± y directions, i.e., δ₃=(Δt₃⁺-Δt₃^-)/2. The phase diagram is analyzed in the space of the electron density (n) and δ₃. The results show that the p- and d-channel superconductivities are respectively enhanced in the low and high electron density regions
