| Abstract: |
| The dual definition of crossed product is introduced.The isomorphism of special case between crossed coproducts coalgebra and twist coproduct coalgebra is considered.The question when two crossed coproducts are equivalence as coalgebra is discussed. |
| Key words: coalgebra crossed coproducts equivalence inner coaction |
