广义超几何函数的表示与不等式

Representations and inequalities for generalized hypergeometric functions

Dmitrii Karp

摘要:

通过广义Stieltjes变换、Laplace变换和余弦傅里叶变换,统一了已知的表示,找到了广义超几何函数的整表示.利用正性条件的重量在这个表示,我们建立各种新的事实,广义超几何函数,包括完全单调性,对数凸性的上参数,单调性的比率和新的证明卢克的界限。此外,我们还利用Bessel型超几何函数的级数表示,得到了它们的双边不等式。

英文摘要:

We find an integral representation for the generalized hypergeometric function unifying known representations via generalized Stieltjes, Laplace and cosine Fourier transforms. Using positivity conditions for the weight in this representation we establish 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. Besides, we derive two-sided inequalities for the Bessel type hypergeometric functions by using their series representations.
