| 研究実績の概要 |
We investigated the multiplicity of eigenvalues of a sun-type quantum graphs.
Also we consider the dissipative wave propagation problem on an infinite star graph. Results obtained are summarized soon and will be submitted to publish.
Also we investigated an inverse problem for elliptic operator in 3 dimensional domain via single measurement

2: おおむね順調に進展している
理由
Research is generally going according to schedule.
|
| 今後の研究の推進方策 |
We hope to extend our results to the problem on more general infinite graphs. For this purpose we need to develop more precise and delicate estimates for spectral and scattering problems on these graphs.

| 次年度使用額が生じた理由 |
Incurring amount will be used according to originally proposed plans in the line with current situation.
