FDE2 - Fractional differential equations

Despite its importance in mathematics, complex analysis is a field which has not been much explored from the fractional viewpoint. Complex-order fractional differintegrals are well known; fractional differintegrals of complex functions are also fairly standard; but many of the specialised facts and operations of complex analysis have had no fractional analogues. We consider the Wirtinger derivatives (in particular, the complex d-bar derivative) and how to define fractional versions of these operators. To motivate and justify the definitions, we compare their properties both with the original d-bar and Wirtinger derivatives and with the original fractional calculus, noting that the natural analogues emerge as expected. Potential applications will also be discussed. Joint work with Chaima Bouzouina.
