Decreasing and complete monotonicity of two functions defined by three derivatives of a completely monotonic function involving the trigamma function
Hong-Ping Yin, Ling-Xiong Han, Feng Qi
In the paper, by convolution theorem of the Laplace transforms, a monotonicity rule for the ratio of two Laplace transforms, Bernstein's theorem for completely monotonic functions,…
Geometry of Kirkwood-Dirac classical states: A case study based on discrete Fourier transform
Ying-Hui Yang, Shuang Yao, Shi-Jiao Geng +2
The characterization of Kirkwood-Dirac (KD) classicality or non-classicality is very important in quantum information processing. In general, the set of KD classical states with re…
The new concepts of ether and calculation of the cosmological constant
Xiao-Song Wang
Since the general theory of relativity (GR) meets some difficulties, it seems that new considerations on the ether theories of gravitation in the history are needed. A theory of gr…
Effect of out-of-plane acoustic phonons on the thermal transport properties of graphene
J. Chen, Y. Liu
The lattice thermal conductivity of graphene is evaluated using a microscopic model that takes into account the lattice's discrete nature and the phonon dispersion relation within…
Asymptotic expansions of truncated hypergeometric series for
Lorenz Milla, Chao-Ping Chen
In this paper, we consider rational hypergeometric series of the form \[\frac{p}π= \sum_{k=0}^\infty u_k\quad\text{with}\quad u_k=\frac{\left(\frac{1}{2}\right)_k \left(q\right)_k…
