Abstract In this paper, we obtain a new estimate of an irrationality measure of the number log 3 . We have μ ( log 3 ) ≤ 5.1163051 with an “arithmetical method”. The previous results were μ ( log 3 ) ≤ 8.616 … by G. Rhin in 1987 and μ ( log 3 ) ≤ 5.125 … by V.H. Salikhov in 2007. 
On the Irrationality Measure of ln 7
Using an integral construction based on symmetrized polynomials, we obtain a new estimate for the irrationality measure of the number In 7. This estimate improves a result due to Wu, which was provedExpand
On Irrationality Measure of arctan $$\frac{1}{3}$$13
We investigate the arithmetic properties of the value arctan $$\frac{1}{3}$$13. We elaborate special integral construction with the property of symmetry for evaluating irrationality measure of thisExpand

Let $s_a(n)$ denote the sum of digits of an integer $n$ in the base $a$ expansion. Answering, in a extended form, a question of Deshouillers, Habsieger, Laishram, and Landreau, we show that, providedExpand
The total distance for totally positive algebraic integers
Let \(P(x)\) be a degree \(d\) polynomial with zeros \(a_1\), \(\ldots\), \(a_d\). Stulov and Yang [‘An elementary inequality about the Mahler measure’, Involve 6(4) (2013), 393–397] defined theExpand
ON MULTIPLICATIVE COMPOSITIONS of INTEGERS
We consider an arithmetic function defined independently by John G. Thompson and Greg Simay, with particular attention to its mean value, its maximal size, and the analytic nature of its DirichletExpand

The arithmetic properties of the values of hypergeometric function have been studied by various methods since the paper of C. Siegel in 1929. This direction of the theory of DiophantineExpand
