ABRIDGED VALEDICTORY LECTURE

Abstract

I first started my academic career as a Junior Fellow in the Depart-
ment of Mathematics in the University of Nigeria, Nsukka, (UNN)
in 1974, after obtaining my BSc Honours degree in Mathematics
as the best graduating student in Physical Sciences in June 1973.
After teaching in Nigeria for a few years, I got Anambra State
Government scholarship and proceeded to Queen's University in
Kingston, Ontario, Canada, where I obtained my rst MSc degree
in Mathematics. Then, I went to Iowa State University briefly before proceeding to The Ohio State University in Columbus, Ohio,
USA where I obtained a second MSc degree and PhD degree in
Mathematics, in June, 1984. I returned immediately after and as-
sumed duties here at the University of Nigeria (UNN) on 5th July,
1984.
