Synthesis of global convergence and adaptivity for a hyperbolic coefficient inverse problem in 3D
Artikel i vetenskaplig tidskrift, 2010
A globally convergent numerical method for a 3-Dimensional Coefficient Inverse Problem for a hyperbolic equation is presented. A new globally convergent theorem is proven. It is shown that this technique provides a good first guess for the Finite Element Adaptive method (adaptivity) method. This leads to a synthesis of both approaches. Numerical results are presented.
