SUMMARY
The discussion centers on identifying a function f: R² -> R that satisfies homogeneity, specifically f(av) = a(f(v)) for all a in R and v in R², while failing to meet the criteria for additivity, f(v + w) = f(v) + f(w). The proposed solution f((x,y)) = x^(1/3)*y^(2/3) successfully demonstrates homogeneity without additivity. The alternative attempt, f((x,y)) = x² + y², fails to satisfy the homogeneity condition, confirming the complexity of finding such functions.
