Homogeneous strict polynomial functors as unstable modules (1407.5964v2)
Published 22 Jul 2014 in math.AT
Abstract: A relation between Schur algebras and Steenrod algebra is shown in [Hai10] where to each strict polynomial functor the author associates an unstable module. We show that the restriction of Hai's functor to the subcategory of strict polynomial functors of a given degree is fully faithfull.
