A short survey on mathematical work of Cemal Koc

Abstract

first met Cemal Koç during Spring semester of 1977. He was then a young associate professor at the Middle East Technical University, Ankara, and I was a Ph.D. student attending his graduate course on noncommutative rings. I had previously attended lectures in Germany given by leading experts on several topics in algebra, yet the course I took that year from Cemal Ko¸c was the one that has left a strong impression on me as a live example of how one should lecture and teach. Later, on many other occasions, I had the chance to observe his enthusiasm for and dedication to teaching. Being a first grade researcher as well, he possessed a combination of talents that one does not find very often. Unfortunately, I won’t be able to give you a taste of what his teaching was like but instead I shall try to summarize his mathematical research.
