摘要：
Possible connections between the inhomogeneities responsible for the Lyman-alpha forest in quasar spectra and gravitational lensing effects are investigated. For most models of the Lyman-alpha forest, no significant lensing is expected. For some versions of the CDM model-based minihalo hypothesis, gravitational lensings on scales less-than-or-similar-to 0".1 would occur with a frequency approaching that with which ordinary galaxies cause arcsecond scale lensing.
