The African Mathematics Millennium Science Initiative (AMMSI) calls for nominations for
Since 2016, the AMMSI-Phillip Griffiths Prize is awarded annually to an African mathematician, living in Africa, who has made outstanding contribution to mathematics, application of mathematics or promotion of mathematics, as evidenced by research and impact of the work. In 2018, the AMMSI-Phillip Griffiths Prize has been awarded to Professor Khalil Ezzinbi from Université Cadi Ayyad, Faculté des Sciences Semlalia, Département de Mathématiques, Marrakesh, Morocco.
Professor Ezzinbi has made many significant contributions to the theory of ordinary differential equations, In addition, he has contributed to other areas of mathematics, including abstract harmonic analysis, dynamical systems and ergodic theory, partial differential equations, operator theory and control theory. His publications in these fields number upwards of 170.
He has, in particular, been cited for his important contributions to the theory of almost automorphic functions, introduced in the early 60’s by Solomon Bochner. This class of functions turns out to generalize the concept of almost periodicity. Most of the periodic physical and environmental processes are not periodic, but periodic up to some bound ε. Application of this theory to evolution equations has attracted many researchers ranging from theoretical mathematicians to biologists, economists, physicists, etc. In recent years the concept has been further generalized to the so-called `weighted pseudo’ almost automorphic functions, but the fundamental problem of the completeness of the space of such classes remained open. A few years later Professor Ezzinbi introduced a new and powerful measure-theoretic method to resolve this open problem. Since then, this method has been used in various classes of evolution equations as well as stochastic differential equations. It has become a truly popular method.
Another significant contribution of Professor Ezzinbi is the use of the so-called subvariant functional method of Fink to prove the existence of compact almost automorphic solutions in certain settings. Here again he positively resolved difficult questions that go back to Amerio and Prouse in the early 60’s.
Professor Ezzinbi remains highly respected within the international mathematical community. From his professional home in northern Africa, his works have inspired many researchers and influenced many publications in several countries around the world. In addition, he has contributed to the future of mathematics in Africa by guiding Ph.D. students to successful careers in the African continent in a number of countries including Morocco, Senegal, Tchad, Nigeria, Cameroun, Burkina Faso, Tunisia and Algeria.
Training & Education
Research is essential for discovery of knowledge and the application of the findings for the benefit of society. It is rare for faculty members in Africa to have sufficient funds, or time from teaching and administrative duties, to perform their own research.
One of the highest priorities of the AMMSI is to provide the opportunity to do so and, where appropriate, to support demonstrations of the application of mathematical work to societal needs.
Linkages & Networks
In Africa, the practice and teaching of mathematics are gravely hampered by the relative isolation of mathematicians from one another. This isolation is largely a function of the small population of mathematicians and the large distances between them.
The AMMSI intends to support linkages, networks, and movement of mathematicians that can foster more collaborative activities and, to some extent, combat the relative isolation of mathematicians.
