Preface
This booklet is dedicated to Professor Shin-ichi Nakagiri and ProfessorTakao Nambu, Kobe University, on the occasions of their 60th birthdays. Aseveryone knows, the both professors have been making challenging contribu-tions in intersection areas of applied mathematics and control theory.
To celebrate these professors’ 60th birthdays a conference, titled as
“Workshop on Mathematical Control Theory in Kobe”
was held on January 8–10, 2010 at Takikawa Memorial Hall, Kobe Univer-sity with more than 30 participants, including scholars from foreign countries.Papers presented in this conference are included in this booklet.
Professor Nakagiri and Professor Nambu have kept active and strong vi-talities in their spirits. We look forward to their long and healthy life and toperpetual contributions. On behalf of the contributors, we heartily dedicatethis booklet to our great colleagues Professor Shin-ichi Nakagiri and ProfessorTakao Nambu.
