Exact essential norm of generalized Hilbert matrix operators on classical analytic function spaces

We compute the exact value of essential norm a generalized Hilbert matrix operator acting on weighted Bergman spaces Avp and Banach Hv? analytic functions, where v is general radial weight. In particular, we obtain classical standard A?p for p>2+?,??0, Korenblum H?? 0<?<1. also cover Hardy space Hp,1<p<?, case. case, equal to conjectured its similarly in case coincide. Hw?? with weights w?(z)=(1?|z|)? all Also this values
