On uniqueness in the inverse obstacle problem via the positive supersolutions of the Helmholtz equation
Masaru Ikehata
This paper is concerned with an inverse obstacle scattering problem of an acoustic wave for a single incident plane wave and a wave number. The Colton-Sleeman theorem states the un…
The enclosure method for inverse obstacle scattering over a finite time interval: VI. Using shell type initial data
Masaru Ikehata
A simple idea of finding a domain that encloses an unknown discontinuity embedded in a body is introduced by considering an inverse boundary value problem for the heat equation. Th…
Remarks on Lin-Nakamura-Wang's paper
Masaru Ikehata
Theorem 1.2 in their paper arXiv:1904.00999v1 [math.AP] 30 Mar 2019 "Reconstruction of unknown cavity by single measurement" is not valid.
On reconstruction from a partial knowledge of the Neumann-to-Dirichlet operator
Masaru Ikehata
We give formulae that yield an information about the location of an unknown polygonal inclusion having unknown constant conductivity inside a known conductive material having known…
On reconstruction in the inverse conductivity problem with one measurement
Masaru Ikehata
We consider an inverse problem for electrically conductive material occupying a domain in . Let be the conductivity of , and a subdomain of . We assume…
Extraction formulae for an inverse boundary value problem for the equation
Masaru Ikehata
We consider an inverse boundary value problem for the equation in a given bounded domain at a fixed . and denote the conductivity an…
