A note on the algebra of operations for Hopf cohomology at odd primes

Let p be any prime, and let B(p) be the algebra of operations on the cohomology ring of any cocommutative F_p-Hopf algebra. In this paper we show that when p is odd (and unlike the p=2 case), B(p) cannot become an object in the Singer category of F_p-algebras with coproducts, if we require that coproducts act on the generators of B(p) coherently with their nature of cohomology operations A Note on the Algebra of Operations for Hopf Cohomology at Odd Primes.
