AMCS Seminar| The Effects of Almost Periodic Environments Upon Population Dynamics

Start Date: January 22, 2018
End Date: January 22, 2018

By Prof. Toka Diagana (Howard University's Mathematics Department in Washington, DC, USA) & (King Fahd University of Petroleum and Minerals )
The main objective of this talk consists of discussing about the effects of almost periodic environments upon population dynamics. That is, we study future life-history evolutions in these environments. In order to do that, we make extensive use of dichotomy techniques to find sufficient conditions for the existence of globally attracting almost periodic solutions to systems of difference equations. These existence results are then applied to discretely reproducing populations with and without overlapping generations.
Biography: Prof. Toka Diagana was born and raised in Kaedi, Mauritania. He received his PhD in mathematics from the Université Claude Bernard – Lyon 1, France in 1999 and then joined the Howard University Mathematics Department in August 2000 as a faculty. He became a tenured full professor in July 2007. He served as the Director of Graduate Studies of the Howard University mathematics department for 8 years. He so far directed 8 PhD students (7 in the U.S. and one in Morocco). His former students currently serve in the following areas: U. S. Department of Defense, Academia, Industry, and Financial Market. His research interests are in differential and partial differential equations, operator theory, difference equations, stochastic differential equations, integrodifferential equations, and p-adic spectral theory. He has authored over 140 research articles and 6 books in mathematics (three of which were published by Springer). Diagana is the founding editor of the "African Diaspora Journal of Mathematics”, the managing editor of both "Communications in Mathematics Analysis"and "Journal of Abstract Differential Equations and Applications", the editorin- chief of “Nonautonomous Dynamical Systems” (De Gruypter), and serves as an associate editor for many other mathematical journals. Professor Diagana is a recipient of the Mauritanian wellknown “Prix Chinguitt”. (The Prix Chinguitt in sciences is a national prize awarded yearly to reward the merits of either a citizen of Mauritania or of another country for major research achievements in sciences. The prize was awarded to Professor Diagana in December 2006 during an official ceremony in Nouakchott before the President of Mauritania and the diplomatic corps.) Diagana is also a recipient of the 2006 Howard University’s Emerging Scholar award. In 2011, he received the “Medal of National Recognition” from the President of Mauritania. In 2009, Professor Diagana was elected as a Fellow of The African Academy of Sciences. In April 2016, he received the “Faculty Excellence Award” from Howard University for his “Achievements in Research”. In September 2016, Diagana joined the King Fahd University of Petroleum and Minerals in Dhahran, KSA, as an adjunct professor. In March 2017, Diagana was elected as the President of the Mauritanian Mathematical Society (PROMATH).
