摘要
The initial boundary value problem for a class of hyperbolic equation with nonlinear dissipative term u(tt) - Sigma(n)(i=1) (partial derivative/partial derivative x(i))(vertical bar partial derivative u/partial derivative x(i)vertical bar(p-2)(partial derivative u/partial derivative x(i)))+ a vertical bar u(t)vertical bar(q-2)u(t) = b vertical bar u vertical bar(r-2)u in a bounded domain is studied. The existence of global solutions for this problem is proved by constructing a stable set in W-0(1,p)(Omega) and show the asymptotic behavior of the global solutions through the use of an important lemma of Komornik.
