Abstract
We study primitive stable representations of free groups into higher rank semisimple Lie groups and their properties. Let \(\Sigma \) be a compact, connected, orientable surface (possibly with boundary) of negative Euler characteristic. We first verify \(\sigma _{mod}\)-regularity for convex projective structures and positive representations. Then we show that the holonomies of convex projective structures and positive representations on \(\Sigma \) are all primitive stable if \(\Sigma \) has one boundary component.
