Species isomorphisms of fibered Burnside rings
Benjamín García
In this note, we present a notion of species isomorphism for fibered Burnside rings. We prove that a species isomorphism can be restricted to an isomorphism of mark tables, that it…

Essential support of Green biset functors via morphisms
Benjamín García
We present a very natural but yet useful criterion to detect vanishing of essential algebras of a Green biset functor by means of morphisms. We introduce the morphisms $Inf:A \…
