In addition, we give some results about left invariant quasi-Sasakian structures on Lie groups of dimension five, whose Lie algebras are nilpotent. Moreover, subclasses of quasi-Sasakian structures are studied for some certain classes.en5-dimensional nilpotent Lie algebraAlmost contact metric structureQuasi-Sasakian structureArticle6813263332618-6470
