| Outline of Annual Research Achievements |
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

| Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
Research is generally going according to schedule.
|
| Strategy for Future Research Activity |
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.
|
| Causes of Carryover |
Incurring amount will be used according to originally proposed plans in the line with current situation.
