【講演者】Jinpeng Lu 氏 (University of Helsinki)
【場所】東大数理126号室
【時間】10:30-11:30
【タイトル】Quantitative stability of Gel'fand's inverse problem
【アブストラクト】Inverse problems study the determination of the global
structure of a space or coefficients of a system from local
measurements of solutions to the system. The problems are originally
motivated from imaging sciences, where the goal is to deduce the
structure of the inaccessible interior of a body from measurements at
the exterior. A fundamental inverse problem, Gel'fand's inverse
problem, asks to determine the geometry of a Riemannian manifold from
local measurements of the heat kernel. In this talk, I will explain
how the unique solvability of the classical Gel'fand's inverse problem
can be established on manifolds via Tataru's optimal unique
continuation theorem for the wave operator. Next, I will discuss our
recent works on the uniqueness and stability of the inverse problem
for the Gromov-Hausdorff limits of Riemannian manifolds with bounded
sectional curvature. This talk is based on joint works with Y.
Kurylev, M. Lassas, and T. Yamaguchi.
