... supported, and it is 21 We have a few assumptions on f(u, x) and w(x). There are four assumptions F1, F2, F3, F4 on f, and two W1, W2 on w. As one can find out soon, they are general enough, and have ... right-continuous, and thus, is continuous. By (11) and (14), we have ηk ≤ f u (0, x) ≤ k, and so −(1 −η) k ≤ f u (0, x) −k ≤ 0 for every 10 Figure 1: Infinite beam on nonlinear a...
