| 英文摘要 | Consider a Kirchhoff plate partial derivative(2)(t)u + Delta(2)u - partial derivative(2)(t)Delta u = 0 in Omega x (0, T), with boundary data u = Delta u = 0 on partial derivative Omega x (0, T) and unknown initial data u(., 0) = u(0) and partial derivative(t)u(., 0) = u(1) in Omega. We study an inverse problem of determining (u(0), u(1)) from an interior observation u vertical bar(w) x(0, T). Here Omega is a bounded domain,. a nonempty open subset of Omega, and T > 0 a suitable time duration. By means of an iterative time reversal technique, we derive an asymptotic formula of reconstructing ( u0, u1) approximately with a logarithmical convergence rate for smooth initial data. The convergence becomes uniform and exponential when (Omega, w, T) satisfies the geometric control condition introduced by Bardos, Lebeau, and Rauch. |
