Topic:

Motivic cohomology and infinitesimal group schemes

Description:

For k a perfect fi eld of characteristic p > 0 and G a split reductive group over k with p a
non-torsion prime for G, we compute the mod p motivic cohomology of the geometric classifying
space BG_(r), where G_(r) is the rth Frobenius kernel of G. Our main tool is a motivic version
of the Eilenberg-Moore spectral sequence, due to Krishna.
