Chi-squared analysis of the combined BATSE/PVO peak flux distribution places constraints on the luminosity function of gamma-ray bursts in a Λ=0,Ω0=1 Friedmann cosmology with a non-evolving density distribution. The analysis indicates that the minimum burst luminosity, the maximum burst luminosity, or both, are constrained, with the opposite end of the luminosity function often unconstrained. For this cosmological model, a non-zero width of the intrinsic luminosity function is preferred, but luminosity functions are forbidden that let many bursts from an extremely broad luminosity range be observed.
