φ -δ-Primary Hyperideals in Krasner Hyperrings

In this paper, we study commutative Krasner hyperrings with nonzero identity. phi-prime, phi-primary and phi-delta-primary hyperideals are introduced. The concept of delta-primary hyperideals is extended to phi-delta-primary hyperideals. Some characterizations of hyperideals are provided to classify them. The relation between phi-delta-primary hyperideals and other hyperideals is discussed.
