Representations and inequalities for generalized hypergeometric functions
D. B. Karp Far Eastern Federal University, Vladivostok, Russia
Abstract:
An integral representation for the generalized hypergeometric function unifying known representations via generalized Stieltjes, Laplace, and cosine Fourier transforms is found. Using positivity conditions for the weight in this representation, various new facts regarding generalized hypergeometric functions, including complete monotonicity, log-convexity in upper parameters, monotonicity of ratios and new proofs of Luke's bounds are established. In addition, two-sided inequalities for the Bessel type hypergeometric functions are derived with use of their series representations.
Key words and phrases:
generalized hypergeometric function, Meijer's $G$-function, generalized Stieltjes transform, Laplace transform, complete monotonicity, log-convexity, Luke's inequalities.
