“…Since then, Euler, too, had researched the topic on the hypergeometric series, but the first full systematic study was introduced by Gauss [12]. Some works and complete references concerning both the hypergeometric series and the certain equation 2can be found in Kummer [13], Riemann [14], Bailey [15,16], Chaundy [17], Srivastava [18], Whittaker [19], Beukers [20], Gasper [21], Olde Daalhuis [22,23], Dwork [24], Chu [25], Yilmazer et al [26], Morita et al [27], Abramov et al [28], Alfedeel et al [29], and the literature therein. However, in contrast to the extensive studies on Equation 2, other hypergeometric differential equations with k ∈ R + are very limited.…”
