Abstract: | We study the asymptotic behaviour ast tends to + of the solution of (u/t)–Lu+(u)–0,u|=0 whereL is a second order self-adjoint elliptic operator and a maximal monotone graph of . If |(r)|/|r|2L1 (-1, 1) and 1 is the first eigenvalue ofL we prove thatu(.,t) converges uniformly on to some element of Ker (L + 1I) and that the limit is nonzero if |(r)|/|r| is nondecreasing. We give also some properties of the limit (monotonicity, continuity, range). |
