About

Thank you for visiting Kenichiro Umezu's Webpage.

I am Kenichiro Umezu (no Keni-chiro, but Ken-ichiro), now a Professor in Department of Mathematics, Faculty of Education, Ibaraki University (shortly called "Iba-Dai"), Mito, Ibaraki, Japan.

I was born in Maebashi, Gunma, Japan on 29 March, 1965. I graduated from Saitama Prefectural Kasukabe High School(shortly called "Kasuko") in 1983 and then graduated from College of Natural Sciences, First Cluster of Colleges, University of Tsukuba, Ibaraki in 1988. I had interested in Analysis of Mathematics since I was an undergraduate student. Among other things, I had a great interest in Functional Analysis and Nonlinear PDE under the supervisor Professor Kazuaki Taira.

I have finished the Doctoral Program of Mathematics in University of Tsukuba on March, 1993 and then received a Doctorate of Mathematics.

Before moving to Ibaraki University on April, 2008, I was Research Associate in Institute of Mathematics, University of Tsukuba, in 1993-1997, Assistant Professor in 1997-2001 in Faculty of Engineering, Maebashi Institute of Technology, Gumma, Japan, and Associate Professor in 2001-2008. On April in 2008, I have moved to Mito City, Ibaraki Prefecture, and I was Associate Professor in Faculty of Education, Ibaraki University in 2008-2012, and then, I have been promoted to Full Professor on April in 2012.

My research interest includes nonlinear partial differential equations. I am interested in steady state problems, or nonlinear elliptic boundary value problems arising from natural phenomena, e.g., population dynamics, chemical combustion, and fermentation. The tools that I prefer to use in analyzing nonlinear problems are purely mathematical, which are those from nonlinear functional analysis, i.e., fixed point theory, iteration scheme, variational method, Lyapunov-Schmidt procedure scheme, implicit function theorem, bifurcation theory, degree theory, and so on. I'm so glad if you could visit Papers for my works.

I lived in Toyohama, Kagawa in 1965-1969, Nishi-Ohita, Ohita in 1969-1973, Saginomiya, Nakano, Tokyo in 1973-1976, Kasukabe, Saitama in 1976-1984, Tsukuba, Ibaraki in 1984-1997, and then, Maebashi, Gunma in 1997-2008. Since 2008, I have been living in Mito, Ibaraki, the 7th place in my life. Where should I move next after in Mito ? Anyone, please tell me about it.

I like playing sports. I prefer Baseball, tennis, table-tennis, soccer, jogging, walking, and weight-training. I enjoyed jogging and participated every year in the 10km running road race "KATSUTA" before. But, now I prefer racewalking. I have a great techniacal interest in racewalking. I also love very much fountain pens. Fountain pens make me rich and happy always. Recently, I bought a digital device. It's very nice, and I want to use it to make a lot of papers.

The Logo appearing in the upper left corner of this webpage was created by my son in the course on information in 2012 when he was of the 1st grade in a junior high school.

Thank you for taking your time, and I look forward to meeting you somewhere in near future. (07 Dec. 2017)
