It is well known that the solution becomes extinct in finite time Τ, i.e., u(x, t) becomes identically zero for t ≥ T, where T is some positive number. In this paper we study the profile of x → u(x, t) as t → T.engjournal articlehttp://www.sciencedirect.com/science/article/pii/0022247X87900138http://www.sciencedirect.comrestricted access517.956.4517.9Semilinearstrong absorptioninitial-boundary value probleminitial datanonnegativeEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
