Using this grand-in-aid, we organized seberal conferences of small size and of middle size. We studied the theory of partial differential equation, theoretically and concret problems in our daily life. The investigators shared the fields of problems and all the participants co-operated in integrating the researchs by organized by investigators.As we wrote in the above, we aimed to develope study of problems of partial differential equation in our daily life, and forcused the study to the inverse problems of partial differential equations, and developed the theoretial approach to these problems. Concerning the inverse problems, we experienced Kobe great earthquake during the period of our research. In fact, one of our main problem of research is a theoretical study of the inverse problem for the elastic wave, that is, the problem to determine the state of earth from the observation of the wave of earthquake. Even though Japan is a country of many earthquake, there are very few researcher in Mathematics. We have to develope the study of this inverse problems. Needless to say, we have to co-operate earth scientists, but we have to multiply the number of mathematicians interested in various problems related to earthquake.

利用这个大手笔，我们组织了一些小型和中型会议。我们学习了偏微分方程的理论，理论和日常生活中的具体问题。研究人员分享问题的领域，所有参与者通过研究人员的组织合作整合研究。如上所述，我们的目标是开展日常生活中偏微分方程问题的研究，并将研究强加于偏微分方程逆问题，并发展了这些问题的理论方法。关于反问题，我们在研究期间经历了神户大地震。事实上，我们研究的主要问题之一是弹性波反问题的理论研究，即根据地震波的观测确定地球状态的问题。尽管日本是一个多地震的国家，但数学研究人员却很少。我们必须发展对这一反问题的研究。不用说，我们必须与地球科学家合作，但我们必须成倍增加对各种与地震有关的问题感兴趣的数学家。
