Nearest-neighbor (NN) tight-binding models (TBMs) on plaquette-centered $\{ 10,3\}$ (Schl\"afli symbol), $\{ 8,3\}$, and $\{ 8,4\}$ hyperbolic lattices on a Poincar\'e disk with open boundary conditions display a vanishing, a finite, and a diverging density of states (DOS) near zero energy (band center), respectively,...
