Query: The extension algebra of some cohomological Mackey functors   Let $k$ be a field of characteristic $p$. We construct a new inflation
functor for cohomological Mackey functors for finite groups over $k$. Using
this inflation functor, we give an explicit presentation of the graded algebra
of self extensions of the simple functor $S_\un^G$, when $p$ is odd and $G$ is
an elementary abelian $p$-group.
