Abstract: Steenrod operations have been defined by
Voedvodsky in motivic cohomology in order to show the Milnor
and Bloch-Kato conjectures. These operations have also been
constructed by Brosnan for Chow rings. The purpose of this
paper is to provide a setting for the construction of the
Steenrod operations in algebraic geometry, for generalized
cohomology theories whose formal group law has order two. We
adapt the methods used by Bisson-Joyal in studying Steenrod
and Dyer-Lashof operations in unoriented cobordism and mod 2
cohomology.
