Symmetric degenerations are not in general induced by type A degenerations
Magdalena Boos, Giovanni Cerulli Irelli
We consider a symmetric quiver with relations. Its (symmetric) representations of a fixed symmetric dimension vector are encoded in the (symmetric) representation varieties. The or…

On degenerations and extensions of symplectic and orthogonal quiver representations
Magdalena Boos, Giovanni Cerulli Irelli
We discuss degenerations of symplectic and orthogonal representations of symmetric quivers and algebras with self-dualities. As in the non-symmetric case, we define a partial order…
