| Paper | : | A new approach to solving of inverse problems of frequency sounding: 'convexification:: of objective function via Carleman weight function |
| Comments | : | This is a joint paper with Dr. Alexandre Timonov
Conventional least squares objective functions for coefficient inverse problems are multiextremal. This makes it extremely difficult to find a global minimum, which corresponds to the solution of the problem. Thus, solution of the inverse problem depends strongly on the accuracy of the estimate of the target coefficien. An accurate estimate, in turn is usually unknown. In this new aproach the original inverse problem is reduced first to a boundary value problem for a non-linear integro-differential equation, in which the unknown coefficient is not present. Next, a least squares objective function is constructed for the latter problem. The key role in this function is played by the weight function, which is involved in the Carleman estimate for the Laplace operator. A surprising result is that this objective function is strictly convex on a certain compact set. Thus, the multiextremality is no longer a problem. An important part of the paper is due to numerical studies, which demonstrate feasibility of this new approach. It is our hope that by the time of the talk, a globally convergent numerical method will also be in place. This approach can be applied to a broad class of coefficient inverse problems. |

| Comments | : | A Widely Convergent Generalized Pulse-Spectrum Technique for 2-D Acoustic Wave Equation Inversion Combining with Plane-Wave Seismograms with Well Logs
G. F. Feng ,B. Han, J. Q. Liu (Department of Mathematics, Harbin Institute of Technology, Harbin,150001, China) Generalized Pulse-Spectrum Technique (GPST) is a kind of widely applied and effective method for solving inverse problem of geophysical prospecting. But it has many shortcomings in convergence domain, ability of anti-noise, computation cost and choice of regularized parameter. So the widely convergent generalized pulse-spectrum technique is introduced and studied for the inverse problem on 2-D wave equation in the seismic prospecting in detail. In this paper we try to construct a new perfect method for the inverse problem on 2-D wave equation. First, combining widely convergent homotopy method applied to the inversion process of operator identification and Tikhonov regularization method for ill-posed problem we introduce Regularization-Gauss-Newton method and Widely Convergent Generalized Pulse-Spectrum Technique (WCGPST). Especially the latter is widely convergent, stable and able to restrain noises. Second, the well log is introduced in the 2-D wave equation inversion for Widely Convergent Generalized Pulse-Spectrum Technique (WCGPST). The relative numerical simulations indicate the robustness of the methods is improved with the increase of the known information. The inversion methods given in this paper synthetically overcome the defects of ordinary generalized pulse-spectrum technique to some extent and have meaningful significance in theory and practice. Key Words: inverse problem of geophysical prospecting; nonlinear inversion; 2-D wave equation inversion; generalized pulse-spectrum technique; constraint inversion |
