研究Hopfπ-余代数H上的π-余模代数的π-余模(右)理想的性质,定义了Hopfπ-余代数H上的π-余模代数的π-余模(右)理想,在局部有限维条件下证明其与π-H*-模右余理想的对偶关系,并讨论了π-余模代数的π-余模理想,给出π-余模理想的等价条件.
Let H be a Hopf π-coalgebra. The notions of π-H-comodule (right) ideal for a π -H- comodule algebra A are introduced. For a local finite dimensional π -H-comodule algebra A, the authors discuss the duals of a π-H-comodule (right) ideal, and obtain some necessary and sufficient conditions for a π-H-comodule (right) ideal.
