Pythagorean Fuzzy Level Subgroup Cut Set Structures

In this paper, we study a new concept, (α,β)-level of pythagorean fuzzy subgroup which different from fuzzy groups, intuitionistic fuzzy group, (2,1)-fuzzy subgroups. Also we define a new kind of pythagorean fuzzy subgroup and its level cut sets. Finally, some properties of pythagorean fuzzy subgroups are studied.
