摘要
Let D subset of R-d be a bounded domain in the d-dimensional Euclidian space Rd with smooth boundary Gamma = partial derivative D. In this paper we consider exponential boundary stabilization for weak solutions to the wave equation with nonlinear boundary condition: {u(tt)(t) - rho(t)Delta u(t) + b(x)u(t)(t) = f(u(t)), u(t) - 0 on Gamma(0) x (0,T), partial derivative u(t)/partial derivative v + gamma(u(t)(t)) - 0 on Gamma(1) x (0,T), u(0) - u(0),u(t)(0) - u1, where parallel to u(0)parallel to < lambda(beta) E(0) < d(beta), where lambda(beta), d(beta) are defined in (21), (22) and Gamma= Gamma(0) boolean OR Gamma(1)and Gamma(0) boolean AND Gamma(1) = phi.
