| 研究実績の概要 |
Last fiscal year, within the scope of my research plan on plasticity (which consists of 3 parts: (A) convergence rates, (B) particle annihilation and (C) atomistic models), I got 2 papers published, 1 accepted and 2 submitted; all to highly respected peer-reviewed journals.
The first published paper is about a proper mathematical description for particle systems involving impenetrable barriers, it is a helpful for project (A). The second published paper provides a new model for dislocation curve dynamics, which fits to the theme of plasticity. The accepted paper is on boundary layers appearing in particle pile-ups, which is an application of project (A). The first submitted paper is on singular dynamical systems, which helps with understanding project (B). The second submitted paper is on the hydrodynamic limit of stochastic particle systems, which fits to project (C).

2: おおむね順調に進展している
理由
Several of the goals in the proposal have been met in the already published and submitted papers. The results in these papers reveal that the more ambitious parts of the proposal are harder to tackle. However, they have also revealed that there are additional interesting problems to study related to the projects (A), (B) and (C) in the proposal. I am currently working on 5 such problems.

| 今後の研究の推進方策 |
I will continue the 5 problems mentioned in the "Current Status" section, and hope to submit them as papers to highly respected peer-reviewed journals in the coming fiscal year. I expect those papers to open up new possibilities for further development of projects (A), (B) and (C) in the proposal.

| 次年度使用額が生じた理由 |
Since the border measures remained very strict due to the corona pandemic, there was no opportunity for business trips abroad and little opportunity for business trips inside Japan. Therefore, I did not spend all the money as attended from fiscal year 2021.
In fiscal year 2022 I intend to use the additional budget from last year to buy a powerful computer to perform simulations with a high computational capacity.
