Soul of circuit theory. A review on research activities of graphs and circuits in Japan

摘要

This paper reviews research activities in the area of topological aspects of circuit theory in Japan, most of which have been done after the previous report of H. Watanabe in the Special Centennial IEEE Transactions on Circuits and Systems, January 1984 issue, and presents main results obtained by Japanese circuit theorists. Throughout these research activities, it can be seen that the soul of circuit theory inherited from Dr. Sidney Darlington has played a backbone role.
