| contents | Let $k=\mathbb{C}(\!(ε)\!)$ be the field of complex Laurent series. We use Galois descent techniques to show that the simple regular representations of the species of type $(1,\, 4)$ over $k$ are naturally parametrized by the closed points of $\mathrm{Spec}(k[x])\dot{\cup}\{1,\,2\}$. Moreover we provide weak normal forms for those representations. We use our representatives of the simple regular representations to describe the canonical algebras associated to the species of type (1, 4) over k. This suggest a model of those algebras in the sense of the work of Geiss, Leclerc and Schröer [GLS17] and [GLS20]. |
