Thank you for visiting Kenichiro Umezu's Webpage.

I am Kenichiro Umezu, now a Professor of the 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 from College of Natural Sciences, First Cluster of Colleges, University of Tsukuba, Ibaraki in 1988. I had interested in and studied Mathematics when I was a undergraduate student. I especially 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 from University of Tsukuba.

Before moving to Ibaraki University on April, 2008, I was a Research Associate in the Institute of Mathematics, University of Tsukuba, during 1993-1997, and after moving to Maebashi, Gunma, an Assistant Professor, during 1997-2001, and an Associate Professor, during 2001-2008, in the Faculty of Engineering, Maebashi Institute of Technology. After moving to Mito, Ibaraki, I was an Associate Professor in the Faculty of Education, Ibaraki University, until March, 2012, and then, has been promoted to a Full Professor on April, 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, with linear and nonlinear boundary conditions. Main tools used for analyzing nonlinear problems are purely mathematical, which are from nonlinear functional analysis, i.e., fixed point theory, iteration scheme, variational method, Lyapunov-Schmidt procedure, implicit function theorem, bifurcation theory, degree theory, and so on. I appreciate it if you could visit List of Publications 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, Maebashi, Gunma in 1997-2008, and have been living in Mito, Ibaraki, the 7th place in my life, since 2008. After in Mito, where do I live ? Nobody knows if... Anyone, tell me about it.

I like to play sports. I prefer Baseball, tennis, table-tennis, soccer, jogging, walking, and weight-training. I enjoyed before jogging every a couple of days and participated in a 10km road race for running, "the KATSUTA", every year. But, now walking around his home is favorite for him. He has a plan to join the KATSUTA next year. He will start running again for it this spring. Can you trust it ? But, now walking is nice for me. Jogging is too heavy for me to continue. I also loves very much fountain pens, being more than 30 or 40. Fountain pens make me rich and happy always. Recently, I bought a digital device, very nice. I like to use it and wish to make a lot of papers with this device.

If you have little interest in mathematics, my works, or even myself, then I apologizes for it. In this case, you are strongly recommended to visit another page. Thank you for your attention and I look for meeting you somewhere in near future. (07 Dec. 2017)
