On the Irrationality Measures of Certain Numbers. II
For the irrationalitymeasures of the numbers $$\sqrt {2k - 1} $$2k−1 arctan$$\left( {\sqrt {2k - 1} /\left( {k - 1} \right)} \right)$$(2k−1/(k−1)), where k is an even positive integer, upper boundsExpand
On Catalan’S constant
A new efficient construction of Diophantine approximations to Catalan’s constant is presented that is based on the direct analysis of the representation of a hypergeometric function with speciallyExpand
Irrationality measure of the number
Using a new integral construction combining the idea of symmetry suggested by Salikhov in 2007 and the integral introduced by Marcovecchio in 2009, we obtain a new bound for the irrationality measureExpand
Symmetrized version of the Markovecchio integral in the theory of Diophantine approximations
A new integral construction unifying the idea of symmetry proposed by Salikhov in 2007 and the integral introduced by Markovecchio in 2009 is considered. The application of this construction leads,Expand
Quadratic irrationality exponents of certain numbers
The paper presents upper estimates for the non-quadraticity measure of the numbers $\sqrt {2k + 1} \ln ((k + 1 - \sqrt {2k + 1} /k)$ and $\sqrt {2k - 1} arctg(\sqrt {2k - 1} /(k - 1))$, where k ∈ ℕ.Expand

The group structure for ζ(3)
1. Introduction. In his proof of the irrationality of ζ(3), Apéry [1] gave sequences of rational approximations to ζ(2) = π 2 /6 and to ζ(3) yielding the irrationality measures µ(ζ(2)) < 11.85078. ..Expand
