Lattice models based on supercells of honeycomb lattice with single-hole defect are studied. The lattice models also include the local Coulomb interaction and the spin-orbit coupling. A two-parameters tight-binding model is used to calculate the band structure and the edge magnetism which appears at the boundary of the hole defects in the lattice. Due to the hole defects a band flatness occurs in the band structure. A competition between band flatness, magnetism and topology is revealed.
