The number of Fuzzy subgroups of some non-abelian groups

Abstract

In this paper, we compute the number of fuzzy subgroups of some classes of non-abeilan groups. Explicit formulas are given<br />for dihedral groups $D_{2n}$, quasi-dihedral groups $QD_{2^n}$, generalized quaternion groups $Q_{4n}$ and modular $p$-groups $M_{p^n}$.
