Comment on “Band structures and optical spectra of InN polymorphs: Influence of quasiparticle and excitonic effects”

In a recent paper, Furthm\"uller et al. [Phys. Rev. B 72, 205106 (2005)] reported results of calculations of the band structure and optical spectra of InN polymorphs that included influence of quasiparticle and excitonic effects. We show below calculated results that disagree with their utilization of the $pd$ repulsion to make significant corrections to band gaps obtained with their ab initio density-functional calculations.
