Abstract
It is established in Chap. 5 that the nonlinearity causes the blow-up to occur at a finite time in certain situations. If the solution to the ODE \(u_t \,= \,f(u)\), blows up at a finite time t = T with \(u(T - 0) = +\infty\), then u = G(T - t), where \(G(\xi)\) is the inverse function of \(\int\nolimits_\infty^u \frac {dn}{f(n)}\)
