Abstract
AbstractWe prove that a word hyperbolic group whose Gromov boundary properly contains a 2‐sphere cannot admit a projective Anosov representation into , . We also prove that a word hyperbolic group that admits a projective Anosov representation into is virtually a free group or virtually a surface group, a result established independently by Dey–Greenberg–Riestenberg.
