  Here we have studied the ideas of $ sg_\lambda,s\lambda$ and $ s\beta_\lambda
$-closed sets and investigated some of their properties in generalized
topological spaces. We have also studied some low separation axioms namely $
s\lambda T_\frac{1}{4} $, $ s\lambda T_\frac{3}{8} $, $ s\lambda T_\frac{1}{2}
$ axioms and their mutual relations with $ s\lambda T_0 $ and $s\lambda T_1 $
axioms.
