Abstract
We investigate the dispersion relations of strained as well as complex Lieb lattices systematically based on the tight-binding method when the nearest-neighbor approximation is adopted. We find that edge states will no appear for strained Lieb lattices and -symmetry Lieb lattice cannot be obtained.

The edge state is controversial and the density of state should be discussed, therefore we plan to withdraw it for a promotion
