has attracted the attention of several authors. In [1], Anderson and Qiu showed that f increases on the interval [1,∞[ and they conjectured that f is concave on the interval [1,∞[. The concavity of f on [1,∞[ was established by Elbert and Laforgia ([3]). At the Fifth International Symposium on Orthogonal Polynomials, Special Functions and Applications held… CONTINUE READING
