WebThe full version of the Riesz representation theorem can be proved in a few lines: The map Φ: H → H ∗ given by y ↦ ⋅, y is a conjugate linear isometric isomorphism. By Cauchy-Schwarz ‖Φ(y)‖ ≤ ‖y‖. Since ‖y‖2 = y, y = [Φ(y)](y) we have equality, hence Φ is isometric. Thus, the only point that deserves elaboration is the fact that Φ is onto. Frigyes Riesz was a Hungarian mathematician who made fundamental contributions to functional analysis, as did his younger brother Marcel Riesz.
