A partial $A_{\infty}$ -structure on the cohomology of $C_{n} \times C_{m}$

Mikael Vejdemo-Johansson

Suppose k is a field of characteristic 2, and $n, m \geq 4$ powers of 2. Then the $A_{\infty}$ -structure of the group cohomology algebras $H^{*} (C_{n}, k)$ and $(H^{*} (C_{m}, k)$ are well known.…
