Evaluation of the real parts of polylogarithm expressions containing complex arguments via certain logarithmic integrals [PDF]
We consider a polylogarithm expression containing complex arguments, namely šĀ±(n)=ā(Liā((1±i)/2)). The central notion of the present paper is to evaluate the real parts of šĀ±(n) for first four orders, specifically n = 1,2,3, and 4, by constructing ...

On approximating the modified Bessel function of the second kind
In the article, we prove that the double inequalities Ļ e ā x 2 ( x + a ) < K 0 ( x ) < Ļ e ā x 2 ( x + b ) , 1 + 1 2 ( x + a ) < K 1 ( x ) K 0 ( x ) < 1 + 1 2 ( x + b ) $$ \frac{\sqrt{\pi}e^{-x}}{\sqrt{2(x+a)}}< K_{0}(x)< \frac{\sqrt{\pi }e^{-x}}{\sqrt ...

Completely monotonic functions involving the gamma and $q$-gamma functions [PDF]
The authors provide new examples of logarithmically completely monotonic functions. These examples are ratios of products involving the Gamma function or the \(q\)-Gamma function. As an application of these results new examples of infinitely divisible probability distributions can be obtained.
