Mod 2 Cohomology groups of spaces are modules over Steenrod algebra, the Hopf algebra generated by Steenrod squares.
It is wellknown that there are too many modules over generic modular Hopf algebras to be classified while invertible modules are small enough to the classification.
In this talk I will explain the related notions and our recent results concerning the classification of invertible modules over certain Hopf subalgebras of Steenrod algebra.
