# Remarks on Lin-Nakamura-Wang's paper

## TL;DR

This paper critically examines a previous theorem related to cavity reconstruction, asserting that the theorem in question is invalid, thereby questioning the validity of the original results.

## Contribution

The paper provides a critical analysis showing the invalidity of a key theorem in prior work on cavity reconstruction from a single measurement.

## Key findings

- Theorem 1.2 is not valid.
- The critique impacts the validity of the original reconstruction method.
- Highlights the need for revised theoretical foundations.

## Abstract

Theorem 1.2 in their paper arXiv:1904.00999v1 [math.AP] 30 Mar 2019 "Reconstruction of unknown cavity by single measurement" is not valid.
