Tangent spaces of orbit closures for representations of Dynkin quivers of type D

Grzegorz Bobinski, Grzegorz Zwara

Let $\mathbb{k}$ be an algebraically closed field, $Q$ a finite quiver, and denote by ${\mathrm{rep}}_Q^{\mathbf{d}}$ the affine $\mathbb{k}$-scheme of representations of $Q$ with a f…
