We introduce a notion of relative curvature (resp. Euler characteristic) for finite rank contractive Hilbert modules over CF + n , the complex free semigroup algebra generated by the free semigroup F + n on n generators. Asymptotic formulas and basic properties for both the curvature and the Euler c
