【Abstract】 With the help of Hǒlder norm, a kind of K functional is introduces, with which a new kind of interpolation type Besov space is established by the K method. The Saturation of Jackson operator is presented successfully by the Besov space. It is the first time that the saturation of an operator has been presented with an interpolation space. The classic well known saturation theorem for the Jackson operator is a special case of the results obtained.更多还原
