In this paper, we investigate and study the notion of left 
-biflatness of abstract Segal algebras, where is a character on Banach algebra. Precisely, we give a necessary and sufficient condition for left -biflatness of abstract Segal algebras equipped with a left approximate identity. As an application, we show that if 
is a Segal algebra on the locally group 
and 
is a character, then is left 
-biflat if and only if is amenable. Indeed, this is a generalization of [4, Theorem 3.4]. Moreover, we study the relationship between left -biflatness and inner -amenability and show that if the Banach algebra 
is inner -amenable, then the notions of left -biflatness and left -amenability are equivalent../files/site1/files/71/10.pdf
