Pythagorean Fuzzy Sublattices and Ideals

In this research paper, we introduce the concepts of Pythagorean fuzzy sublattices and Pythagorean fuzzy ideals within the context of a lattice. We proceed to establish various properties associated with these Pythagorean fuzzy sublattices and ideals. Moreover, we introduce the notion of (γ, δ) level set and (γ, δ) strong level sets, accompanied by relevant theorems. Lastly, we define Pythagorean fuzzy convex sublattices and engage in a discussion concerning their properties.
