IntroductionIf / , g are real functions such thatoo0 < 5 f2(x)dx0(1.1)oo< oo a n d 0 < \ g2(x)dxo< oo,then we have the following well known Hilbert's integral inequality [1],oo oo f(\ \56\ ( \S[X)9{y)x +dxdyy00f°°1/2< 7T< \ f \ x ) d x \ g\x)dxU6\iwhere the constant factor 7r is the best possible. Furthermore, we have alsothe following Hardy-Hilbert's type inequality [1, Th 341, Th 342],00 00ooooi 0S 566g X'x~yf(r)n(iA,0gyf(x)g(y)dxdy00r°°11/2soooo< t t 2 \ \ f ( x ) d x \ g\x)dxU6>| 1/2J,where the constant factors 4 and 7r2 are both the best possible.There are numerous literatures to study the Hilbert's and Hardy-Hilbert'stype inequalities from different directions [4, 5, 6, 7].
