基于歐拉函數(shù)的其他特殊函數(shù)完全單調(diào)性證明
[Abstract]:Complete monotonicity and logarithmic complete monotonicity are important properties of Gamma functions. The complete monotonicity of other special functions based on Euler function is proved and studied. The complete monotonicity of some special functions including Gamma functions is proved and some important inequalities are derived. First of all, by using the unit group of integer ring theory and the properties of the theory itself, the coprime properties of special functions are described. The form of integer ring prime element, the expression of integer prime element and the expression of partial non-integer prime element are given. According to the properties of quotient rings of integer rings, the mutual prime properties of special functions are analyzed by means of isomorphic mapping. Secondly, under the properties of special functions containing Gamma functions, According to the properties of Euler function, the complete monotone property of special function containing Gamma function is proved. The condition that every order derivative of any Euler function is a positive integer in a certain interval is proved. If the positive function of any Euler function also satisfies the positive integer, it is proved that the special function is completely monotone in a certain interval.
