Cauchy’s integral formula via the modified Riemann-Liouville derivative for analytic functions of fractional order. (English) Zbl 1202.30068
Summary: The modified Riemann-Liouville fractional derivative applies to functions which are fractional differentiable but not differentiable, in such a manner that they cannot be analyzed by means of the Djrbashian fractional derivative. It provides a fractional Taylor series for functions which are infinitely fractional differentiable, and this result suggests to introduce a definition of analytic functions of fractional order. Cauchy’s conditions for fractional differentiability in the complex plane and the Cauchy integral formula are derived for these kinds of functions.
