Keywords:Hardy-Hilbert""s inequality, parameter, weight coefficient, equivalent form, operator expression.
Abstract:
      By introducing independent parameters and applying the weight coefficients, we give an extended Hardy-Hilbert""s inequality in the whole plane with a best possible constant factor. Furthermore, the equivalent forms, a few particular cases and the operator expressions are considered.
