Abstract: It is argued that the fractional operators naturally appear in certain modeling approaches, especially when the governing equations have terms that mimic certain "frictional-type of effects." So, two questions we struggle to answer are that "when and why fractional operators appear in model equations?" In the quest of finding answers to these questions, in this talk we study some properties of a generalized fractional integral which unifies six familiar fractional integrals into a unique form given by
We obtain a series representation of this integral along with asymptotic expansion and use it to solve a time-fractional porous medium equation in a subdiffusive case (0 < α < 1) of the form
Bio: Udita N. Katugampola is an assistant professor of mathematics at Florida Polytechnic University (FL Poly). His primary research areas are in fractional calculus and combinatorics with the intension of finding “real world” applications of fractional operators. One of his major achievements is the unification of Riemann-Liouville and Hadamard fractional operators into a unique form, which is now known in the literature as “Katugampola fractional integral” that has many applications in applied mathematics and other areas. He also received a U.S. Army research grant in the amount of $300k for his work on fractional calculus. After graduating from Southern Illinois University at Carbondale, he joined Delaware State University as a visiting assistant professor before joining University of Delaware and now he is with FL Poly as a faculty member.
