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 on 29 March, 1965, in Maebashi, Gunma, Japan. I graduated from Saitama Prefectural Kasukabe High School(shortly called "Kasuko") in 1983, and then, 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, receiving a Doctorate of Mathematics at the same time.

Before moving to Ibaraki University on April, 2008, I was a Research Associate in the Institute of Mathematics, University of Tsukuba, in 1993-1997, and then, an Assistant Professor in 1997-2001 and an Associate Professor in 2001-2008 in Faculty of Engineering, Maebashi Institute of Technology, Gumma, Japan. Then, I have moved to Mito City, Ibaraki Prefecture, and I was an Associate Professor in Faculty of Education, Ibaraki University in 2008-2012, and then, I have been promoted to a 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 from nonlinear functional analysis, i.e., fixed point theory, iteration scheme, variational method, Lyapunov-Schmidt procedure scheme, implicit function theorem, bifurcation theory, degree theory. I'm 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 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)
