α-Differentiable functions in complex plane

In this paper, the conformable fractional derivative of order a is defined in complex plane. Regarding to multi-valued function z(1-alpha), we obtain fractional Cauchy-Riemann equations which in case of alpha = 1 give classical Cauchy-Riemann equations. The properties relating to complex conformable fractional derivative of certain functions in complex plane have been considered. Then, we discuss about two complex conformable differential equations and solutions with their Riemann surfaces. For some values of order of derivative, alpha, we compare their plots.
