We obtain an inequality for the weight coefficient ω(q,n)
(q>1, 1/q+1/q=1, n∈ℕ) in the
form ω(q,n)=:∑m=1∞(1/(m+n))(n/m)1/q<π/sin(π/p)−1/(2n1/p+(2/a)n−1/q) where 0<a<147/45,
as n≥3; 0<a<(1−C)/(2C−1), as n=1,2, and C is an Euler
constant. We show a generalization and improvement of Hilbert's
inequalities. The results of the paper by Yang and Debnath are
improved.
