A Complex parameters of 1F1 resulting in real values

  1. Jun 27, 2017 #1
    The confluent hypergeometric function $$_1F_1(a,b,x)$$ satisfies
    By using this relation (and that the complex conjugate of the hypergeometric function is the same as taking the complex conjugate of all its arguments), it can be easily shown that the function
    is equal to its complex conjugate. My question is if there is some other representation for this function f? Is it equal to some other "famous" special function? Since it is a purely real function, I would imagine that there might exist some representation of it that does not involve complex numbers.
