Primary hyperideals of multiplicative hyperrings
In this article, we study prime, primary, C-hyperideals of multiplicative hyperrings in the sense of Rota . Prime hyperideal avodiance lemma was proved in . We mainly study union of primary hyperideals in hyperring. Among many results in this study we give the primary hyperideal avodiance lemma. Also we determine all prime, primary, C-ideals of quotient hyperring.
