A Course of Algebra (PART I)

Abstract

The following is an exposition of a course of algebra that Prof. Aleksandr Aleksandrovich Zykov (1922-2013) distributed among the participants of his seminar in graph theory not far away from Odessa, Ukraine, on September, 1991. It is a privilege for me to be able to reproduce, with some good additions, the English version of this remarkable course that he designed carefully over several years with the help of other colleagues and with the only purpose of making the science of algebra more accessible to the less gifted student. Prof. Zykov was an admirable person and a very clever mathematician and scientist. His scientific interests were wide: from the mathematical sciences at any level and in any of their branches to the theory of relativity as I recall. He kindly wrote a review recommending the results of my doctoral dissertation, which was necessary for the approval to obtain a Ph.D. degree during the meeting of my defense. In that meeting, I was very nervous because I had in front of me fifteen professors all of them doctors of technical or mathematical sciences asking all sort of questions and whom I had to convince of the fact that my results were true. I am sure this algebra course played the role that Prof. Zykov, with his deepness of thought, had primarily intended, that is, one course designed with the right approach to help out many of his students.
