... Hilbert, and Courant was carried forward in the U.S. by Fritz John, James Stoker, and Kurt Friedrichs, and they and their students developed many impor- tant ideas that reached beyond rigorous differential ... H(p)W, where H(p)=(RCp + 1) −1 . This formula should be interpreted as one for the transforms of V and W: V ∗ = H(p)W ∗ , and so V (t) is the inverse Laplace transform of...
