We introduce the notion of TL-P*-subgroups which is an extension of the notion of TL-P*-subgroups and investigate basic properties of TL-P*-subgroups. And we consider decompositions of TL-subgroups.

We introduce the notion of TL-p-subgroups that is an extension of the notion of fuzzy p-subgroups and show that a torsion TL-subgroup of an Abelian group with T=∧ can be written as the intersection of its minimal TL-p-subgroups.

We introduce the notion of TL-p-subgroups that is an ex-tension of the notion of fuzzy p=subgroups and show that a torsion TL-subgroup of an Abelian group with T=${\bigwedge}$ can be written as the intersection of its minimal TL-p-subgroups.

In this paper, we show that if a TL-subgroup can be written as the intersection of all its minimal TL-p-subgroups then some properties of the TL-subgroups characterize the properties of all its minimal TL-p-subgroups and investigate the properties of the join of a directed family of TL-subgroups.
