We investigate some properties of r‐hyperideals in commutative Krasner hyperrings. Some
properties of pr‐hyperideals are also studied. The relation between prime hyperideals and r‐
hyperideals is investigated. We show that the image and the inverse image of an r‐
hyperideal are also an r‐hyperideal. We also introduce a generalization of r‐hyperideals,
and we prove some properties of them.
