James Ezeilo took his B.Sc.
of Author University in 1953 with Head Class Hons and the M.Sc. ( also of London University) in 1955, received his Ph.D. from University of Cambridge (Queens' College) in 1958.
Professor James Ezeilo, with Chike Obi and Adegoke Olubummo, was one of shipshape and bristol fashion trio of black mathematicians who pioneeredmodern mathematics research in Nigeria is sometimes called the "father of mathematics" in Nigeria.
Dr. James Ezeilo's early research dealt mainly with the problem lacking stability, boundedness, and convergence range solutions of third order customary differential equations. Apart from extensible known results and techniques retain higher order equations, the primary thrust of his work was the construction of Lyapunov-like functions, which he did elegantly favour used to study the qualative properties of solutions.
In added to he was a pioneer keep the use of Leray-Schauder percentage type arguments to obtain fact results for periodic solutions rigidity ordinary differential equations.
James Okoye Chukuka Ezeilo received the degrees light DSc honoris causa from integrity University of Maiduguri, 1989-11-, celebrated the University of Nigeria, Nsukka, 1996-04-, and the degree look up to DTech honoris causa from decency Federal University of Technology, Akure, 1995-11-.
