“…Definition 2.1. If the function ( ) is analytic (regular) inside and on , where 37 = { − , + }, − is a contour along the cut joining the points and −∞ + Im( ), 38 which starts from the point at −∞, encircles the point once counter-clockwise, and 39 returns to the point at −∞, and + is a contour along the cut joining the points and 40 ∞ + Im( ), which starts from the point at ∞, encircles the point once counter-41 clockwise, and returns to the point at ∞, 42 43 is Euler's function gamma (Oldham and Spanier, 1974;Miller and Ross, 1993;Podlubny, 1999;Yilmazer and Ozturk, 2013).…”
