| Abstract: |
| A kind of new K-functional is introduced with the help of Holder norm,with which the divect theorem and the inverse theorem of a kind of trigonometrical interpolatory operator are characterized. |
| Key words: besov space interpolation space interpolatory operator bounded linear operator |
