Let $A$ be a Green biset functor. A seed is a pair $(H,V)$ consisting of a group $H$ for which the essential algebra $\widehat{A}(H)$ is non-zero and a simple $\widehat{A}(H)$-modu…

A minimal group for a Green biset functor is a group of smallest order on which the functor is nonzero. The isomorphism conjecture. The minimal groups for a Green biset functor sho…

Let $A$ be a Green biset functor. For a group $H$, let $I_A(H)$ be the submodule of $A(H\times H)$ generated by composites $a\circ b$, where $a\in A(H\times K)$,…
