Abstract

Let nN2n \in \mathbb{N}_{\geq 2}. We prove that for every k4k \geq 4 there exist uniform but non-homogeneous Steiner bundles on Pn\mathbb{P}^n of kk-type with disconnected splitting type, and we further investigate almost-uniform Steiner bundles. Our approach relies on interpreting Steiner bundles as relative projective Kronecker representations and applying adjoint pairs arising from restriction, inflation, and reflection functors.
