STEENROD REDUCED POWERS IN THE SPECTRAL SEQUENCES ASSOCIATED WITH A FIBERING.

Extended Powers and Steenrod Operations in Algebraic Geometry

Steenrod operations were defined by Voedvodsky in motivic cohomology in order to prove the Milnor and Bloch-Kato conjectures. These operations have also been constructed by Brosnan for Chow rings [5]. 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.

Minimax Problems Related to Cup Powers and Steenrod Squares

If F is a family of mod 2 k-cycles in the unit n-ball, we lower bound the maximal volume of any cycle in F in terms of the homology class of F in the space of all cycles. We give examples to show that these lower bounds are fairly sharp. This paper is about minimax estimates for the volumes of cycles in complicated families. The simplest example of a minimax problem is a classical result about ...
