Some remarks on linear forms containing Catalan’s constant. (Russian) Zbl 1099.11036
The paper deals with the Catalan’s constant \(G=\sum_{n=1}^\infty \frac{(-1)^n}{(2n+1)^2}\). New recurrent sequences of the second order in the form \(r_n=u_nG-v_n\) of the type of Apéry are presented and their asymptotic behavior is proved. The group permutation which is connected with \(G\) is also included. The author concludes that maybe it will be possible to prove the irrationality of the number \(G\) with this tool.
